Datasheet
SDC3106
General Description
Features
SDC3106 is a high performance off-line PSR controller for
Tlow-power AC/DC charger and adapter applications
which integrates 700V power BJT. It works in Pulse
NFrequency Modulation Mode and provides operating Efrequency dithering function to improve EMC
performance of power supply. It operates in primary-side
Msensing and regulation. Consequently, opto-coupler and UTL431 could be eliminated. SDC3106 provides ±5%
constant voltage and constant current regulation at
CONFIDENTIAL DOCuniversal ACinput.
