G2822

Global Mixed-mode Technology

1MHz, 3A Synchronous Step-Down Regulator

General Description

Features

The G2822 is a high efficiency monolithic synchronous

buck regulator using a constant frequency, current

mode architecture. Supply current during operation is

only 50μA and drops to <1μA in shutdown. The 2.7V

to 6.5V input voltage range makes the G2822 ideally

suited for single Li-Ion battery-powered applications.

100% duty cycle provides low dropout operation, ex-

tending battery run time in portable systems. Switching

frequency is internally set at 1MHz, allowing the use of

small surface mount inductors and capacitors. The

internal synchronous switch increase efficiency and

eliminates the need for an external Schottky diode.

Built-in soft start function eliminates in-rush current

that could damage the system.

High Efficiency: Up to 95%
