A power supply is disclosed. The power supply an output diode, a main switch coupled to the input filter and an output inductor coupled to the output diode and the main switch. The power supply also includes a bypass switch coupled to the main switch and configured to bypass the output inductor. A switch driver is included and the switch driver is configured to turn on the bypass switch and upon detecting the output diode in a blocking mode, turn on the main switch and turn off the bypass switch.

SMPS filter optimization

A controller for controlling a power generator circuit, and a method for operation such a controller, is disclosed. The invention is particularly suited to LED current generators. The current generator may be switched off to conserve power when not required for any LED circuits. The method relates to determining the time at which the controller is required to provide power, current or voltage, and to adjust the timing of switching-on of the controller, in order to ensure that power, current or voltage is available for the load when required.
