The LM5156x-Q1 (LM5156-Q1 and LM51561-Q1) device is a wide input range, non-synchronous boost controller that uses peak current mode control. The device can be used in boost, SEPIC, and flyback topologies. The LM5156x-Q1 device can start up from a 1-cell battery with a minimum of 2.97 V if the BIAS pin is connected to the VCC pin. It can operate with the i.
