Product details

Description

The AT1729 is a PWM DC/DC converter control IC with 3 channel outputs that can directly drive power MOSFET.

This IC ia suitable for very small DC/DC converters because of their small and thin package(1.1 mm max.), and high operation frequency (up to 1.0 MHz).

Features

Low input voltage: 2.5V to 7V.
3-Channels PWM Control: 2 Boost Controller(CH1,CH2) 1 Inverting Controller (CH3).
Adjustable Soft start time and maximum duty cycle.
Built-in timer latch for short circuit protection: Delay time=216/(Switching frequency).
Built-in under-voltage lockout, thermal shutdown.
High operating frequency: 100kHz to 1MHz.
