FA7701V

FA7700V, FA7701V s 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. CMOS IC For Switching Power Supply Control FA7700V, FA7701V s Dimensions, mm TSSOP-8 4.4 ±0.2 6.4 ±0.3 s Features Wide range of supply voltage: VCC=2.5 to 20V FA7700V: For boost, flyback converter (Maximum output duty cycle is 80%) FA7701V: For buck converter (Maximum output duty cycle is 100%) Output stage consist of CMOS push-pull circuit, and achieves a high speed switching of external MOSFETs. (FA7700V: For Nch-MOSFET driving, FA7701V: For Pch-MOSFET driving) High accuracy reference voltage (Error amplifier): 0.88V±2% Soft start function Adjustable built-in timer latch for short-circuit protection Output ON/OFF control function Less external discrete components needed (2 components less than conventional version of the equivalent products) Low power consumption Stand-by current: 40µA typ.
