TPS40170-EP Datasheet Wide-input Synchronous Pwm Buck Controller

Manufacturer: Texas Instruments

Overview: www.ti.com TPS40170-EP SLVSBT7A – MARCH 2013 – REVISED APRIL 2013 4.

General Description

TPS40170 is a full-featured, synchronous PWM buck controller that operates at an input voltage between 4.5 V and 60 V and is optimized for high-powerdensity, high-reliability dc-dc converter applications.

The controller implements voltage-mode control with input-voltage feed-forward compensation that enables instant response to an input voltage change.

The switching frequency is programmable from 100 kHz to 600 kHz.
