Driverless step-down controller qualified for automotive applications

07-05-2020 | Texas Instruments | Automotive Technologies

Texas Instruments TPS59632-Q1 Three-Phase Driverless Step-Down Controller comes with advanced features such as D-CAP+ control architecture with output voltage OSR and USR. This gives a very fast transient response, low output capacitance, and high efficiency. The device supports I2C for dynamic control of the output voltage, phase management for optimised efficiency, and current monitor telemetry.


The MOSFET gate driver is created 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 –40C and 125C. The device is AEC-Q100 qualified for automotive applications


Typical applications include ADAS, a conditionally automated drive controllers, and vehicle infotainment and clusters.
