OB3636A Description
OB3636A is a flyback controller with high power factor, low THD and high constant voltage (CV) precision. It can achieve low system cost for an isolated application by primary side control in a single stage converter. It significantly simplifies the CV system design by eliminating the secondary side feedback ponents and the opto-coupler.
