Switched current regulator with improved power switch control mechanism |
摘要 |
A flyback-type switched current regulator, comprising first and second coupled windings and a circuit for connecting the first winding to a voltage source as soon as the windings are demagnetized. The regulator further comprises a current sensor that senses the current flowing through the first winding; a switch that disconnects the first winding from the voltage source when the first current in the first winding reaches a reference value, whereby the first winding is switched according to a duty cycle; and a circuit that varies the reference value in accordance with the duty cycle.
