General Description
The LM3101 is a precision high-speed PWM controller. It is designed to provide secondary-side feedback for offline Switch-Mode Power Supplies (SMPS) using pulse communication to the primary-side driver. The LM3101 is applicable in all of the popular converter topologies such as flyback or forward.

Features
±2% precision voltage reference
Wide-bandwidth (8 MHz) error amplifier
External synchronization
Frequency shift during an output short circuit
Power-on reset flag with programmable delay
Overvoltage crowbar trigger circuit
Ramped reference Soft-Start
Operation beyond 1 MHz
Voltage, current, or charge mode control

Typical Applications
Isolated offline switching power supplies
Isolated DC/DC power converters
Flyback regulator
Forward converter
