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 the many functions equivalent to those which our conventional version bipolar ICs – FA76XX series- have,and have merits of output ON/OFF control function,directly driving Nch/Pch MOSFETs,low power consumption , higher frequency operation, and less external discrete components.
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.)
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) -
