The LM5155x-Q1 (LM5155-Q1 and LM51551-Q1) 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-Q1 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.
