TPS61175PWP

The TPS61175PWP is a High Voltage Boost Converter with soft-start and programmable switching frequency. The device 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 multicell batteries or regulated 5, 12V power rails. The TPS61175 regulates the output voltage with current mode PWM (pulse width modulation) control. The switching frequency of PWM is set by either an external resistor or an external clock signal. The user can program the switching frequency from 200kHz to 2.2MHz. The device features a programmable soft-start function to limit inrush current during start-up and has other built-in protection features, such as pulse-by-pulse over-current limit and thermal shutdown.
