General Description

The UTC US3602 is a primary side control offline LED lighting controller.

It operates in inductor current DCM mode and can achieve accurate constant current.

The UTC US3602 integrates 600V power MOSFET and simplifies the LED lighting system design by eliminating the secondary side feedback components and the opto-coupler.

Key Features

Built-in 600V Power MOSFET.
±3% constant current regulation at universal AC input.
Primary side control without TL431 and opto-coupler.
Programmable CC regulation.
Flyback topology in DCM operation.
Low operating current to improve efficiency.
High resistance feedback resistor to improve efficiency.
LED short and open circuit protection.
Cycle-by-cycle current limiting.
Built-in leading edge blanking.
VCC over voltage protection.
VCC.
