APPLICATION NOTE R9A02G011 RTK-251-BuckBoostConverter2 Instruction Manual R19AN0055EJ0100 Rev.1.0 Nov 9, 2018 Introduction The RTK-251-BuckBoostConverter2 is DC-DC module for a part of a Universal USB Power Delivery (PD) AC adapter utilizing the USB PD 3.0 controller R9A02G011 and Bi-directional Buck-Boost Voltage Regulator ISL95338. This document is an instruction manual for RTK-251-BuckBoostConverter2. The RTK-251-BuckBoostConverter2 accepts 19V with 4.73A DC input power and produces USB PD-compatible VBUS output power. It supports Programable Power Supply (PPS) - USB PD 3.0 ver.1.1 compliant function - and has two USB Type-CTM receptacles for VBUS power output. The RTK-251-BuckBoostConoverter2 was developed to facilitate evaluation of the USB PD 3.0 Controller R9A02G011 and Bi-directional Buck-Boost Voltage Regulator ISL95338. The RTK-251-BuckBoostConverter2 is USB-IF PD3.0 certified and the functions and capabilities are fixed in the setting at that time.

Category: Power Brick (with PPS) Product Name: RTK-251-BuckBoostConverter2 TID: 1000181 Power Role: Source only Port 1: 60W Power Source (5, 9, 12, 15, 20V and 20V Prog) Port 2: 15W Power Source (5V and 5V Prog) Supports BC1.2 DCP R19AN0055EJ0100 Rev.1.0 Nov 9, 2018 Page 5 of 11 R9A02G011 RTK-251-BuckBoostConverter2 Instruction Manual 2. Functions The RTK-251-BuckBoostConverter2 functions are described in this section. 2.1 Programable Power Supply (PPS) function Programable power supply (PPS) is a new feature of USB Power Delivery Rev 3.0 for battery charging. A sink device having a battery requests VBUS voltage and also current directly to charge the battery. This feature achieves the reduction of voltage transformation loss and heat for devices having a battery. In order to realize this feature, a USB PD source device should provide VBUS voltage and also current limit as fine steps. The VBUS voltage rises until either the target voltage is reached or the specified maximum VBUS current is reached. R19AN0055EJ0100 Rev.1.0 Nov 9, 2018 Page 6 of 11 R9A02G011 RTK-251-BuckBoostConverter2 Instruction Manual 2.2 LED indicators RTK-251-BuckBoostConverter2 supports 5 LED indicators. Only three of them are enabled. 1. Orange (D3): System power indicator. LED lights when RTK-251-BuckBoostConverter2 is supplied power from AC adapter (CN6 jack). 2. Blue (D5, D7): VBUS power supply indicator. LED lights when VBUS power is supplied on the USB receptacle. Figure 2-1 LEDs on the RTK-251-BuckBoostConverter2 R19AN0055EJ0100 Rev.1.0 Nov 9, 2018 Page 7 of 11 R9A02G011 RTK-251-BuckBoostConverter2 Instruction Manual 2.3 Protections This section describes the protection features that RTK-251-BuckBoostConverter2 supports. OCP event on either the adapter side or the VBUS side is detected by ISL95338. Then ISL95338 stops output voltage. PDC detects VBUS drop as an OCP event. When PDC detects OCP event more than twice without cable detach, PDC stops VBUS output until PDC is reset by power off. This behavior that stops VBUS output is based on the USB PD standards. OTP event is detected when the temperature near the USB Type-C connector: 1. Exceeds 80 �C, immediately, 2. Exceeds 60 �C, for 1sec. When the event happens, RTK-251-BuckBoostConverter2 disables the power circuitry to stop sourcing power on VBUS. When the temperature becomes lower than 40 �C, RTK-251-BuckBoostConverter2 enables the power circuitry again and starts the power negotiations. When RTK-251-BuckBoostConverter2 detects over temperature again, it does not supply power even if the temperature becomes lower than 40 �C. It is necessary to shut down RTK-251BuckBoostConverter2 once to restart by detaching external power supply (AC adapter).

A-1 General Precautions in the Handling of Microprocessing Unit and Microcontroller Unit Products The following usage notes are applicable to all Microprocessing unit and Microcontroller unit products from Renesas. For detailed usage notes on the products covered by this document, refer to the relevant sections of the document as well as any technical updates that have been issued for the products. 1. Handling of Unused Pins Handle unused pins in accordance with the directions given under Handling of Unused Pins in the manual. The input pins of CMOS products are generally in the high-impedance state. In operation with an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of LSI, an associated shoot-through current flows internally, and malfunctions occur due to the false recognition of the pin state as an input signal become possible. Unused pins should be handled as described under Handling of Unused Pins in the manual. 2. Processing at Power-on The state of the product is undefined at the moment when power is supplied. The states of internal circuits in the LSI are indeterminate and the states of register settings and pins are undefined at the moment when power is supplied. In a finished product where the reset signal is applied to the external reset pin, the states of pins are not guaranteed from the moment when power is supplied until the reset process is completed. In a similar way, the states of pins in a product that is reset by an on-chip power-on reset function are not guaranteed from the moment when power is supplied until the power reaches the level at which resetting has been specified. 3. Prohibition of Access to Reserved Addresses Access to reserved addresses is prohibited. The reserved addresses are provided for the possible future expansion of functions. Do not access these addresses; the correct operation of LSI is not guaranteed if they are accessed. 4. Clock Signals After applying a reset, only release the reset line after the operating clock signal has become stable. When switching the clock signal during program execution, wait until the target clock signal has stabilized. When the clock signal is generated with an external resonator (or from an external oscillator) during a reset, ensure that the reset line is only released after full stabilization of the clock signal. Moreover, when switching to a clock signal produced with an external resonator (or by an external oscillator) while program execution is in progress, wait until the target clock signal is stable. 5. Differences between Products Before changing from one product to another, i.e. to a product with a different part number, confirm that the change will not lead to problems. The characteristics of Microprocessing unit or Microcontroller unit products in the same group but having a different part number may differ in terms of the internal memory capacity, layout pattern, and other factors, which can affect the ranges of electrical characteristics, such as characteristic values, operating margins, immunity to noise, and amount of radiated noise. When changing to a product with a different part number, implement a system-evaluation test for the given product. Notice 1.
