Linear Regulators
Low dropout linear regulators (LDOs) can be used in applications which require to drop a higher input voltage to a lower output voltage at relatively moderate power levels. Richtek has developed a broad portfolio of LDOs which feature high power supply ripple rejection (PSRR) to keep the output voltage free of noise and ripple, low quiescent current (Iq) to extend battery life and different packaging for various power dissipation. Our wide input-voltage LDOs can be applied in industrial applications. The high-performance AEC-Q100 qualified LDOs are ideal for automotive applications.
Richtek LDO's are grouped as following: � General Purpose LDOs with Fixed Output Voltage � General Purpose LDOs with Adjustable Output Voltage � Low Vin Low Vout LDOs with Input Voltage Lower than 6.5V � LDOs with Low Quiescent Current � LDOs with Input Voltage Higher than 6.5V � Automotive Graded LDOs � DDR Memory Terminator LDOs

Low Vin Low Vout LDOs
Low Vin Low Vout LDOs are specially designed for low drop-out voltage in applications with relatively low input voltage. Some of these LDOs require an external low power bias voltage which needs to be at least 1.5V higher than the output voltage and thereby limits the maximum output voltage for these parts. LDOs with internal Charge Pump don't need the external bias voltage and have a wider output voltage range.

LDOs with Low Quiescent Current
LDOs with low quiescent current have an important feature that reduces LDO ground current at light load and helps extend battery life in portable applications. Richtek's low Iq products also have dynamic ground current that will quickly increase ground current when load increases. This helps improve load transient response and is ideal for applications that run in burst mode conditions. All low Iq LDOs are fixed output voltage versions.

LDOs with Input Voltage Higher than 6.5V
LDOs with input voltage higher than 6.5V can be used in applications with wider input voltage range up to 80V. Please note that the LDO power dissipation is (Vin-Vout) * I_load so a high (Vin�Vout) drop will quickly lead to high LDO dissipation at moderate load currents.

DDR Memory Terminator LDOs
DDR memory terminator LDOs have both source and sink functionality and require very tight output voltage regulation. These parts can be used with many types of DDR memory from DDR1 to DDR4 as well as Low Power(LP) DDR3/4. The low Vin LDOs require an external low power bias voltage. Selecting a suitable product for your applications should be based on DDR type, current rating and features such as output voltage sensing, REFOUT and different power state settings via S3 / S5 pins.

Buck Converters
Buck converter control loop topology has great impact on the converter transient behavior, stability criteria and switching frequency behavior. Below overview shows different Buck converter control topologies in the Richtek portfolio and their advantages/disadvantages:
Current Mode Buck
Current Mode COT
High Voltage ACOTTM Buck
Low Voltage ACOTTM Buck
Current mode Buck topology takes several switch cycles to react on load transient. A larger output capacitor (Cout) is required for small V.
Current mode COT Buck topology is faster than pure current mode, but still takes several switch cycles to react on load transient. A larger Cout is required for small V.
ACOTTM reaction speed is almost instantly. Cout can be small for the same V.

General Buck converter features and function description: � PSM parts will automatically skip pulses at light load thereby enhancing light load efficiency, at the expense of
higher ripple and worse transient response in light load range. � Force PWM parts will maintain their nominal switching frequency also at light load, which gives lowest ripple
and best transient response. � 100% Duty-Cycle parts can maintain regulation even at very low Vin-Vout difference, and the part can operate
in drop-out mode which can be useful in battery-powered applications. � External Sync. parts can have their internal switching frequency clock synchronized to an external clock,
making it possible to run several Buck converters at the same frequency and controlling the frequency precisely to avoid noise in certain sensitive frequency bands. � External Soft-Start makes it possible to adjust the converter rise time during start-up via an external capacitor, to reduce inrush currents when using large output capacitors. � External Comp. allows the users to tune the converter control-loop response. This adds extra flexibility in the choice of output capacitors in current mode converters. � Power Good signal can be used to signal other devices that the voltage rail is within specification. It can also be used to drive the enable pin of another converter, thereby giving a specific power sequence during start-up.

Buck-Boost Converters
Buck-Boost converters are used in applications where input voltage can vary, either below or above the output voltage. The four internal MOSFET switches will be automatically configured to form a Buck when VIN exceeds VOUT and change to Boost operation when VIN falls below VOUT. This makes Buck-Boost ideal for battery-powered applications to extend battery life when the battery voltage falls below the regulated output voltage. The efficiency of the Buck-Boost converter is very good because of the fully synchronous operation. The output current capability in Buck mode is normally higher than in Boost mode. This is because the Boost mode requires higher switching current at the same load conditions compared to the Buck mode. The MOSFET voltage ratings will determine the maximum input and output voltage range.

Boost controllers will step up the input voltage to a higher output voltage with external switches. The output current is limited by external MOSFETs which gives designers the flexibility to optimize performance. With Boost controllers, designers can achieve higher levels of output power and operating temperature range that might be not possible with boost converters.

Boost Converters
Boost converters will step up the input voltage to a higher output voltage. This is accomplished by charging an inductor via an internal MOSFET switch and discharging the inductor via a rectifier to the load when the MOSFET switch is off. The current rating of the MOSFET switch together with step-up ratio will determine the maximum load current, and the MOSFET voltage rating will determine the maximum output voltage capability. In some boost converters, the rectifier is integrated as a MOSFET to provide synchronous rectification.

Battery Management
Richtek's battery management products and supporting tools accelerate the design of high efficient and high performance battery-powered applications. Richtek offers a wide range of battery chargers as well as battery gauges and protection devices.
Single Cell Li-Ion Linear Battery Chargers
Single cell Li-Ion battery charger ICs can be used to provide the correct charge current and voltage in batterypowered applications. The battery charger will measure battery charge current and battery voltage and will control the pass MOSFET in such a way that the charge current follows the required battery charge operation modes: pre-conditioning - constant current - constant voltage - current cut-off. The maximum charge current can be programmed by an external resistor, and an NTC coupled to the battery will send the battery temperature information to the charger. Charging status pins will signal the charging condition. Most linear chargers for single cell Li-Ion batteries are fed by 5V supply and are normally used for charge currents up to 1A, suitable for battery cells up to 1Ah.

Battery Fuel Gauge
Richtek's battery gauges use Voltaic Gauge with current sensing (VGCS) to determine the State of Charge, State of Health, Full Charge Capacity, Time to Empty and Cycle Count of Li-Ion cells. They use an internal algorithm to calculate these parameters and communicate it back to the host microcontroller via I2C.
