LM5155x-Q1(LM5155-Q1 and LM51551-Q1),It is a non-synchronous boost controller that adopts peak current mode control and has a wide input range. This device can be used in boost, SEPIC and flyback topologies. If the BIAS pin is connected to the VCC pin, the LM5155x-Q1 can be powered by a single battery (with the minimum voltage of 2.97V). If the voltage at the BIAS pin is higher than 3.5V, this device can use an input power supply voltage as low as 1.5V.
