Key Features

  • For wide input voltage range, LLC current resonant power supply system can be configured without PFC. Integrated high-side and low-side drive circuits, which can be directly connected to the power MOSFET and operates with 50% duty cycle. The integrated startup circuit achieves downsized power supply and lower power consumption. Operating mode can be selected from normal operation mode, low standby mode, and ultralow standby mode (STB pin) During the low standby mode, standby power is lowered by.

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. To ensure high reliability of the power supply, the arm-short prevention function, high-accuracy overload protection function, and overcurrent protection function with adjustable delay time are provided.
