Introduction

AI Translation

The TPS65653-Q1 is designed to provide tight power supply specifications for noise-sensitive applications such as radar. The device integrates two step-down DC/DC converters and general-purpose digital output signals, and is controlled via an I2C-compatible serial interface and enable signals. Auto PWM/PFM (AUTO mode) operation maximizes efficiency across a wide output current range. The TPS65653-Q1 supports remote voltage sensing to compensate for IR drops between the regulator output and the point-of-load (POL), improving output voltage accuracy. In addition, the switching clock can be forced into PWM mode and synchronized with an external clock to minimize interference. The TPS65653-Q1 supports programmable startup and shutdown delays and sequencing, including GPO signals synchronized with the enable signal. During startup and voltage transitions, the device controls the output slew rate to minimize output voltage overshoot and inrush current.
