LM5155 Datasheet (Texas Instruments) - 2.2-MHz Wide Input Nonsynchronous Boost Flyback Controller

LM5155, 2.2-MHz Wide Input Nonsynchronous Boost Flyback Controller

The LM5155x ( LM5155 and LM51551 ) 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 LM5155x device can start up from a 1-cell battery with a minimum of 2.97 V if the BIAS pin is con
