LM5157x/LM5157x-Q1 Boost Flyback & SEPIC Converter

Texas Instruments LM5157x/LM5157x-Q1 Boost Flyback & SEPIC Converter is a wide input range, non-synchronous boost converter with integrated 50V, 6.5A (LM5157/LM5157-Q1) or 50V, 4.33A (LM51571-Q1) power switch. The device can be used in boost, SEPIC, and flyback topologies. The Texas Instruments LM5157x/LM5157x-Q1 can start up from a single-cell battery with a minimum of 2.9V. It can operate with the input supply voltage as low as 1.5V if the BIAS pin is greater than 2.9V. The LM5157x-Q1 devices are AEC-Q100 qualified for automotive applications.
