APPLICATION NOTE
MINIMIZE POWER LOSSES OF LIGHTLY LOADED FLYBACK
CONVERTERS WITH THE L5991 PWM CONTROLLER
by Claudio Adragna


The L5991 PWM controller is particularly suitable for SMPS of equipment that must comply with
standards concerning energy saving. The device, optimized for flyback topology, monitors the power
demanded by the load and changes the operating
