ML4818 Phase Modulation/Soft Switching Controller

The ML4818 is a complete phase modulation control IC suitable for full bridge soft switching converters. Unlike conventional PWM circuits, the phase modulation technique allows for zero-voltage switching transitions and square wave drive across the transformer. The IC modulates the phases of the two.

ML4818 Features

* a 6V hysteresis with a low starting current to allow off-line start up with a low power bleed resistor. A shutdown function powers down the IC, putting it into a low quiescent state. FEATURES s Full bridge phase modulation zero voltage switching circuit with programmable ZV transition times Consta
