iW3626 Off-Line Digital Power Controller for LED Driver with High-Power Factor and Low-Ripple Current 1 Description The iW3626 is a high performance, single-stage AC/DC power controller for LED luminaires with power factor (PF) correction. The device uses digital control technology to build unique hybrid mode control in PWM flyback power supplies to achieve high power factor meanwhile minimizing LED current ripple. This distinctive control approach enables the capability for users to make trade-offs between PF and LED current ripple in a single-stage design. It can achieve excellent LED current regulation over line and load variation, without the need for secondary feedback circuit.
