■Description
The FA5304AP(S) and FA5305AP(S) are bipolar ICs for switching power supply control and can directly drive a power MOSFET. These ICs contain many functions in a small 8-pin package. With these ICs, a high-performance power supply can be created compactly because not many external
components are needed.

■Features
• Drive circuit for connecting a power MOS-FET (IO= ±1.5A)
• Wide operating frequency range (5 to 600kHz)
• Pulse-by-pulse overcurrent limiting function
   Positive voltage detection: FA5304AP(S)
   Negative voltage detection: FA5305AP(S)
• Overload cutoff function (Latch or non-protection mode selectable)
• Output ON/OFF control function by external signals
• Overvoltage cutoff function in latch mode
• Undervoltage malfunction prevention function (ON at 16V and OFF at 8.7V)
• Error amplifier for control by tertiary winding detection
• Low standby current (90µA typ.)
• 8-pin package (DIP/SOP)

■ Applications
• Switching power supply for general equipment
