Abstract:
A switching regulator includes circuitry for reducing conductive emissions caused when the regulators switch from one transistor switch to the other. The switching regulator includes at least one switch with a diode connected from the source to the drain of at least one of the transistor switches. When the regulator switches from one transistor switch to the other, the circuitry initiates turning on the switch with a relatively small, current-limited signal, waits for the diode across the recently turned off switch to complete reverse recovery, and then quickly turns the new switch fully on.
