一,产品概述(General Description)

JTMS9601 IS is an AC-DC primary-sensing off-linecontroller. 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.
二.产品特点(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
三,应用范围 (Applications)

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