Description

FA3687V 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 (up to 1.5MHz). You can select Pch or Nch of MOSFETs driven, and design any topology of DC-to-DC converter circuit like a buck, a boost, inverting, a fly-back, or a forward.
