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.
  • 600mV Reference voltage with 1% accuracy
  • Programmable UVLO and hysteresis
  • Voltage mode control with voltage feed forward
  • Bidirectional-frequency synchronization with master/slave
  • Low-side FET sensing overcurrent protection
  • High-side FET sensing short-circuit protection with integrated thermal compensation
  • Programmable closed loop soft-start
  • Supports pre-biased outputs
  • Thermal shutdown at 165°C with hysteresis
  • Voltage tracking
  • Enable with 1µA Low current shutdown
  • Integrated bootstrap diode
  • Green product and no Sb/Br

Applications

Power Management, Communications & Networking, Industrial

Warnings

Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
