FA7701V-TE1 FUJI Power Supply Control IC

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.) Operating current: 1.2mA(typ.) (including error amplifier output current and oscillator current) ・High frequency operation: 50kHz to 1MHz ・Package: TSSOP-8(thin and small)
