G5934

High Voltage 1.5x Charge Pump with Load Switch

Controller

General Description

Features

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.

Input Range: 8V to 24V

Output Range: 12V to 36V

150µA Quiescent Current at 8V Supply Voltage

and 190µA Quiescent Current at 24V Supply

±3% Regulated Output

Power Good Function

Power Good of Open Drain (Monitor AC V_IN

Only)

The G5934 has a NMOS open-drain output pin for

power good indication. When V^OUT> 1.5 x V_INx 90%,

the NMOS will be turned off immediately and PG pin

will be pulled high by external resistor.

Embedded a 12-V LDO

4 Control Signal Inputs

4 12V-Drivers for external NMOS switches

4 Discharging Networks for 22Ω

Over-Temperature Protection

Output Short Circuit Protection

TQFN3X3-20 Package

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.

Applications

Notebook Computers

The G5934 is available in TQFN3X3-20 package

(thermal pad included).
