Design TPS40170-Q1
SLVSB90B – JANUARY 2012 – REVISED DECEMBER 2014 TPS40170-Q1 4.5-V to 60-V, Wide-Input, Synchronous PWM Buck Controller
1 Features 3 Description The TPS40170-Q1 device 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-power-density, 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. 1 Qualified for Automotive Applications
