Green Mode PWM IC
FA8A00N / 01N
1.Overview
Datasheet
FA8A00N/01N is a current mode type switching power supply control IC possible to drive a power MOSFET directly.
Despite of a small package with 8 pins, it has a lot of functions and it is best suited for power saving at the light load and
decreasing external parts. Moreover it enables to realize a reduced space and a high cost-performance power supply.
2.Features
■ Low standby power
・ Built-in discharge function for X-Capacitor
(Reduce loss of the discharge resistor)
・ Low operating current
(During normal operation Ivccop1=450uA typ.)
・ Reduce of switching frequency at middle load
・ Burst mode at light load
・ Built-in 500V high voltage startup circuit.
■ Various Protection
・ Two-stages Over Load Protection.
5.0 0.25
(Delay time Tdlyolp=70msec typ.)
・ Built-in OLP line compensation
・ Short Circuit Protection for secondary side
・ Latch stop function by pull-up/pull-down of LAT pin.
1.27
・ Over-Voltage Protection(Vthovp=25.5V typ.)
・ Under-Voltage Lock-Out function(Vvccoff=6.5V typ.)
Package:SOP-8
・ Brown-IN/OUT Function
・ Built-in Soft-Start function(Tss=11msec typ.)
・ Built-in Minimum ON width function.
■ Low EMI by Frequency diffusion function
■ Drive circuit for MOSFET: -0.5A(sink)/0.5A(source)
