TOP104YAI - Three-terminal Off-line PWM Switch

Description

The TOPSwitch family implements, with only three pins, all functions necessary for an off-line switched mode control system: high voltage N-channel power MOSFET with controlled turn-on gate driver, voltage mode PWM controller with integrated 100 kHz oscillator, high voltage start-up bias circuit, ba

Features

Auto-restart and cycle by cycle current limiting functions handle both primary and secondary faults.
On-chip latching thermal shutdown protects the entire system against overload Highly Versatile.
Implements Buck, Boost, Flyback or Forward topology.
Easily interfaces with both opto and primary feedback.
Supports continuous or discontinuous mode of operation.
Specified for operation down to 16 V DC input AC IN DRAIN SOURCE.
