All trademarks are the property of their respective owners. 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. For all available packages, see the orderable addendum at the end
of the data sheet.
