Product Overview

The TPS40170RGYT is a synchronous PWM Buck Controller operates at an input voltage between 4.5 and 60V and is optimized for high-power density, high-reliability DC to DC converter applications. The controller implements voltage-mode control with input voltage feed-forward compensation that enables instant response to input voltage change. The switching frequency is programmable from 100 to 600kHz. It has a complete set of system protection and monitoring features such as programmable undervoltage lockout (UVLO), programmable overcurrent protection (OCP) by sensing the low-side FET, selectable short-circuit protection (SCP) by sensing the high-side FET and thermal shutdown. The ENABLE pin allows for system shutdown in a low-current (1µA typical) mode. The controller supports pre-biased output, provides an open-drain PGOOD signal and has closed-loop soft-start, output voltage tracking and adaptive dead-time control.
