The FA531X series are bipolar ICs for switching power supply control that can drive a power MOSFET. These ICs contain many functions in a small 8-pin package. These ICs create a high-performance and compact power supply because not many external discrete components are needed.
-Features
• Drive circuit for connecting a power MOSFET
• Wide operating frequency range (5 to 600kHz)
• Pulse-by-pulse overcurrent limiting function
• Overload cutoff function (Latch or non-protection mode selectable)
• Output ON/OFF control function by external signal
• Overvoltage cutoff function in latch mode
• Undervoltage malfunction prevention function
• Low standby current (90mA typical)
• Exclusive choices by circuits
• 8-pin package (DIP/SOP)
-Applications
• Switching power supply for general equipment
