Current resonant control IC FA6A30/31N Datasheet 1.
Overview FA6A30/31N is a switching power supply control IC for LLC current resonant converter.
This IC enables a LLC current resonant converter for wide input voltage range without PFC.
It incorporates a 600V start up circuit, downsizing the circuit and enabling low-power consumption.
It also incorporates a 600V high-side driver and low side driver, which can drive directly both high-side and low-side MOSFETs with 50% duty cycle alternatively
