iW3628 Product Summary
Off-Line Digital Power Controller for LED Driver with High Power Factor and Low-Ripple Current
1.0 Features
2.0 Description
●● All-in-one non-dimmable low-cost off-line LED driver (isolated and non-isolated applications)
●● Supports universal input
voltage range (90VAC to 277VAC) and output power up to 20W
●● High power factor (PF) with low current-ripple control technology
●● User-configurable power factor setting (>0.7 to >0.9)
●● User-configurable over-temperature protection (OTP) with temperature-current derating
●● Very tight LED current regulation (±5%) across line and load, and within primary inductance tolerance (±20%)
●● Isolated design without opto-coupler
●● Supports wide range of LED numbers with tight current regulation
●● Stabilized LED current-ripple control without visible shimmer or flicker
●● Active start-up scheme enables fastest possible start-up
●● 72kHz maximum PWM switching frequency with qu...
