open-in-new Find other Buck controllers (external switch)


The TPS59632-Q1 device is a three-phase driverless step-down controller with advanced features such as D-CAP+™ control architecture with output voltage overshoot reduction (OSR) and undershoot reduction (USR) providing very fast transient response, lowest output capacitance, and high efficiency. The device supports I2C for dynamic control of the output voltage, phase management for optimized efficiency and current monitor telemetry. The TPS59603-Q1 MOSFET gate driver is designed specifically to accompany this controller to drive the synchronous buck converter powerstage MOSFETs. The TPS59632-Q1 device is packaged in a 5-mm by 5-mm space saving, thermally-enhanced 32-pin, 0.5-mm pitch QFN and is rated to operate at a range between –40°C and 125°C.
