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
