TPS40170-EP 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 pensation that enables instant response to an input voltage change. The switching frequency is programmable from 100 kHz to 600 kHz.
