General Description

The G5632 is a high efficiency, 2A buck converter with

two low RDS(ON) switches. It operates from 5V to 14V

input voltage range, and provides up to 2A continuous

output current with the output voltage adjustable down

to 0.8V. Whenever the load is light, the G5632 automatically change the PWM operation mode to PFM

operation to minimize the power consumption. Hence

it is suitable for battery-powered devices.

The G5632 is available in a SOP-8 package.
