TPS92315 Description

The TPS92315 flyback power supply controller provides isolated output current regulation without the use of an optical coupler. The devices process operating information from the primary power switch and an auxiliary flyback winding to provide precise output current control. Low start-up current, dynamically controlled operating states and a tailored modulation profile support very low stand-by power without...
