FA5304AP Overview
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 pactly because not many external ponents are needed.
FA5304AP Key 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: FA5305A
- 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)
FA5304AP Applications
- Switching power supply for general equipment
