Texas Instruments TPS59632-Q1 Driverless Step-Down Controller

Texas Instruments TPS59632-Q1 Three-Phase Driverless Step-Down Controller comes with advanced features such as D-CAP+™ control architecture with output voltage overshoot reduction (OSR) and undershoot reduction (USR). This provides a 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 power stage MOSFETs. The Texas Instruments TPS59632-Q1 device is packaged in a 5mm x 5mm space-saving, thermally-enhanced 32-pin, 0.5mm pitch QFN. It is rated to operate at a range between –40°C and 125°C.
