TPS61175 3A High Output Boost Converter


Texas Instruments’ TPS61175 is a monolithic switching regulator with integrated power switch

TI's TPS61175 3A High Output Boost ConverterTexas Instruments' TPS61175 is a monolithic switching regulator with integrated 3A, 40V 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 5V, 12V power rails. The TPS61175 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 200kHz to 2.2MHz. 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.
