ML4813CP Datasheet PDF - Micro Linear Corporation

GENERAL DESCRIPTION
The ML4813 is a PWM controller designed for use in a discontinuous "flyback" or "buck-boost" type power factor correction (PFC) system for low power, low cost applications.

FEATURES
■ Precision buffered 5V reference
■ Extra op-amp for output voltage instrumentation amplifier
■ Overcurrent comparator for switch protection
■ Soft start and under-voltage lockout for easy low surge off-line starting
■ 1A peak current Totem-pole output drive
■ Overvoltage comparator eliminates output "runaway" due to load removal
■ Large oscillator amplitude for better noise immunity
