Part number : DAP013F
Functions : SOP13 Pin Package information
The DAP013 offers everything to build high performance AC-DC converters or offline adapters. Thanks to a novel valley lockout system, the controller is able to switch inside the drain-source valley and is immune to valley jumping instabilities. When the output load decreases significantly, the controller toggles to a fixed peak current/variable frequency mode that ensures very low standby power consumption.
