General Description
The G5933 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 56µA at 8V supply and
96µA at 24V supply. The G5933 can deliver 10mA
output current with a voltage drop of 900mV at 24V
supply.
The G5933 has a NMOS open-drain output pin for
power good indication. When VOUT > 1.5 *V_IN* 90%,
the NMOS will be turned off immediately and PG pin
will be pulled high by external resistor.
The G5933 contains an over-temperature circuit to
protect the device under continuous output short cir-
cuit conditions. The device is available in a 8-pin
MSOP package.
