Product Description
TPS40170QRGYRQ1 Automotive Synchronous PWM Buck Controller
The TPS40170QRGYRQ1 is a full-featured synchronous PWM buck controller designed for high-power-density, high-reliability DC-DC converter applications. Operating with an input voltage range of 4.5V to 60V, this controller implements voltage-mode control with input-voltage feed-forward compensation for instant response to input voltage changes. The switching frequency is programmable from 100 kHz to 600 kHz.
