FA7700V General Description
FA7700V/FA7701V are the PWM type DC to DC converter control ICs with 1ch output that can directly drive power MOSFETs. CMOS devices with high breakdown voltage are used in these ICs and low power consumption is achieved.
These ICs have not only the functions equivalent to those of FA76XX series but also the functions of directly driving Nch/Pch MOSFETs, lower power consumption, higher frequency operation, and less external components.
