FA5604/5605/5606
1. Description
The FA5604/05/06 is the PWM type switching power supply control IC that can directly drive power MOSFET. This IC
realizes the low power consumption with reducing the switching frequency at light load. This IC contains many functions
in a small 8-pin package. With this IC, a high-performance and compact power supply can be created because not many
external discrete components are needed.
2. Features
Voltage mode control
Systems organized by circuit methods
FA5604: Applied to forward power supplies (maximum duty cycle = 46%)
FA5605/FA5606: Applied to flyback power supplies (maximum duty cycle = 70%)
Automatically reduces the switching frequency to suppress loss in stand-by mode
The switching frequency can be set (RT pin)
A drive circuit for connecting a power MOSFET directly
Output peak current: +1.0A / -0.5A
Overcurrent of primary side limiting function (IS pin negative voltage sense)
Overload protection function (switching frequency control by VF pin)
Overload protection function (CS pin)
Built-in output overvoltage latch protection (stopping the latch by pulling up the CS terminal by external signals)
Undervoltage lockout function (17.5V ON / 9.7V OFF)
8-pin package (SOP-8)
