ML4828 Datasheet (Micro Linear) - BiCMOS Phase Modulation/Soft Switching Controller

ML4828, BiCMOS Phase Modulation/Soft Switching Controller

The ML4828 is a complete BiCMOS phase modulation control IC suitable for full bridge soft switching converters.

Unlike conventional PWM circuits, the phase modulation technique allows for zero voltage switching (ZVS) transitions and square wave drive across the transformer.

The IC modulates the phas

ML4828 Features

* a 1.5V hysteresis with a low starting current to allow off-line start up with a bleed resistor. A shutdown function powers down the IC, putting it into a low quiescent state. The circuit can be operated at frequencies up to 1MHz. The ML4828 contains four high current CMOS outputs which feature high
