Abstract
A regulator for a blocking oscillator includes overcurrent protection and light-load operation. An error signal derived from sensing output voltages is then summed with an opposite sense ramp voltage at the input of a comparator having a high amount of hysterises. When sufficient ramp voltage is generated to cause the comparator to switch, a pulse is generated to cause the main power switch to turn off. Variations of the error voltage thus causes the ramp time to vary in a way which opposes changes in the voltage at the load.
