The TPS61175-Q1 is a monolithic switching regulator with integrated 3-A, 40-V power switch. It can be configured in several standard switching-regulator topologies, including boost, SEPIC and flyback. The device has a wide input voltage range to support application with input voltage from multi-cell batteries or regulated 5-V, 12-V power rails.
The TPS61175-Q1 regulates the output voltage with current mode PWM (pulse width modulation) control. The switching frequency of PWM is either set by an external resistor or an external clock signal. The user can program the switching frequency from 200-kHz to 2.2-MHz.
The device features a programmable soft-start function to limit inrush current during start-up, and has built-in other protection features, such as pulse-by-pulse over current limit and thermal shutdown. The TPS61175-Q1 is available in 14-pin HTSSOP package with PowerPAD.
