3.Description
The LM5156x-Q1 (LM5156-Q1 and LM51561-Q1)device is a wide input range, non-synchronous boostcontroller that uses peak current mode control. Thedevice can be used in boost, SEPIC, and flybacktopologies.The LM5156x-Q1 device can start up from a 1-cellbattery with a minimum of 2.97 V if the BIAS pin isconnected to the VCC pin. It can operate with theinput supply voltage as low as 1.5 V if the BIAS pin isgreater than 3.5 V
