DESCRIPTION
SIC9601 IS is an AC-DC primary-sensing off-line controller. There needs only very few external components to build a low cost switching power supply with this 3-pin controller. The patented Base-Sense technology incorporates the output driving feature and the input current sensing function together into the shared B/S pin.

FEATURES
· Primary sensing eliminates photo-coupler.
· Single-chip controller with the least external components
· Patented Base-Sense technology to sharing the B/S pin
· Self oscillation eases the coil transformer design with less requirement in precision.
· Constant output power
· Tight constant voltage regulation＜±5%.
· Universal AC input range
· Over-voltage protection

APPLICATION
· Isolated AC-DC power regulator,such as USB chargers,power adapters for both handheld devices and household electrical appliances.
· Isolated LED Power Driver
