Global Mixed-mode Technology Inc.

AT1793

2-Channel Step-Down PWM Controller

Features

General Description

4.75V to 26V supply voltage operating.

Efficiency up to 85%.

AT1793 is a voltage-mode PWM step-down controller

capable of driving loads over a wide input supply

range with excellent line and load regulation charac-

teristics. High efficiency is obtained through the use of

a low Rds(on) P-channel power switch.

Typical frequency operation to 1MHz.

Voltage-mode PWM step-down regulation.

1V±2% internal reference.

Shutdown current less than 30uA.

Soft-start built-in.

It uses a fixed switching frequency up to 1MHz thus

allowing smaller sized components. The output volt-

age level is user-programmable via an external resis-

tive voltage divider. The built-in soft-start can reduce

inrush current on the input source at turn on. The

built-in short-circuit protection can prevent from a

short-circuit.

Short-circuit protection build-in

TQFN3X3-16 & SOP-14 package.

Applications

DC-DC power management.

The AT1793 also has built-in 2 control pins that can

power down the regulator to a shutdown mode. In

shutdown mode the regulator draws less than 30uA of

supply current

AT1793 is available in TQFN3X3-16 or SOP-14 package
