More Information

The TPS43340-Q1 is a quad rail power supply featuring two synchronous Buck Controller with 0.6-A gate drive, one synchronous 2-A Buck Converter and a 300-mA LDO with low quiescent current. The device is designed to power the entire system including MCU and DSP straight from the car battery respectively input voltages up to 40 V. The device features integrated short-circuit and overcurrent protection on the gate-drive outputs for the buck regulator controllers and independent current-foldback control for each buck regulator supply during regulator output short to ground. Each output supply incorporates a soft start to ensure that on initial power up these regulated outputs are not in current limit. Implementation of reset delay on power up allows the outputs of Buck1, Buck2, Buck3 and the linear regulator to get to stable regulation. An external capacitor sets the delay to a maximum range of 300 ms. Each power-supply output has adjustable output voltage based on the external resistor-network settings. The device has sequencing control during power up and power down of the output rails, based on the enable-and-disable control or soft start.
