The L6591 PWM controller is the first integrated controller optimized for zero-voltage switching asymmetrical half-bridge converters, which enable smaller, lower-cost power supplies delivering high efficiency from standby to full load, thereby reducing heat and power loss. The L6591 implements all of the functional blocks necessary to control a soft-switching half-bridge converter. The L6591 implements pulse skipping under light-load and no-load conditions, and has a quiescent current lower than 3mA. The L6591 also provides a PFC interface, allowing the PFC pre-regulator to be turned off to maximize power savings under light- and no-load conditions…
