The LM5157RTER is a non-synchronous boost converter with an integrated 50V power switch and wide input range. The device can be used in boost, SEPIC and flyback topologies. The device can be started from a single battery with a voltage of at least 2.9V. The device can be operated from input supply voltages as low as 1.5V if the voltage at the BIAS pin is above 2.9V, and the BIAS pin can be operated at voltages up to 45V (50V absolute maximum). The switching frequency is dynamically programmable by an external resistor from 100kHz to 2.2MHz.
