Product introduction

The TPS61175 is a 3A high voltage boost converter with soft start and programmable switching frequency

illustrate

The TPS61175 is an integrated 3-A, 40 V power switch monolithic switching regulator. It can be configured in several standard switching regulator topologies, including boost, SEPIC, and flyback. The device features a wide input voltage range input voltage to support applications with multiple cells or regulated 5 V, 12 V rails.

The TPS61175 current mode regulation PWM (Pulse Width Modulation) controls the output voltage. The PWM switching frequency can be either an external resistor or an external clock signal. The user can switch from the program to 200 kHz at a frequency of 2.2 MHz.

The device features a programmable soft-start function to limit inrush current during start-up, as well as built-in additional protection features such as pulse-by-overcurrent limit and thermal shutdown pulse.
