Description

FA3686V is a PWM type DC-to-DC converter control IC with 2ch outputs that can directly drive power MOSFETs. CMOS devices with high breakdown voltage are used in this IC and low power consumption is achieved. This IC is suitable for very small DC-to-DC converters because of their small and thin package (1.1mm max.), and high frequency operation (to 1.5MHz). This IC contains built-in an error amplifier for series regulators, therefore, this IC is suitable for the 3ch power supply with a 2ch DC-to-DC converter and a 1ch series regulator.
