General Description
The G5934 is a high-voltage switched-capacitor
charge pump that provides the regulated output volt-
age of 1.5x input voltage. Input voltages ranging from
8V to 24V can be converted into a 12V to 36V output
supply. The device is ideal for battery-powered con-
version applications in notebook computers with a
typical operating current of 150µA at 8V supply and
190µA at 24V supply.
The G5934 has a NMOS open-drain output pin for
power good indication. When VOUT > 1.5 x VIN x 90%,
the NMOS will be turned off immediately and PG pin
will be pulled high by external resistor.
The G5934 contains an embedded 12-V LDO to pro-
vide the supply voltage to the drivers controlled by ON
signals. The discharging networks are connected to
the 22Ω resistor to shut down the low-voltage system
while control input signals ON are not ready.
The G5934 contains an over-temperature circuit to
protect the device under continuous output short cir-
cuit conditions.
The G5934 is available in TQFN3X3-20 package
(thermal pad included).
