Description
General part information
LM5156-Q1 Series
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 input supply voltage as low as 1.5 V if the BIAS pin is greater than 3.5 V.
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.
