Overview

May 1997 ML4818* Phase Modulation/Soft Switching Controller GENERAL DESCRIPTION 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 sides of the bridge to control output power.
The ML4818 can be operated in current mode.
The delay times for the outputs are externally programmable to allow the zero-voltage switching transitions to take place.
Pulse-by-pulse current limit, integrating fault detection, and soft start reset are provided.
The under-vo...
