iW3630 Description

The iW3630 is a two-stage, high-performance AC/DC offline power supply controller for dimmable LED luminaires with analog dimming interface. It controls LED current based on analog input voltage on the dimming pin. It also has a built-in 0-10V isolation transformer driver which can work directly with 0-10V dimming system without adding extra driver circuit and micro-controller.

iW3630 Key Features

  • Isolated/non-isolated offline 100VAC/277VAC LED driver controller
  • Meets IEC61000-3-2 requirements
  • Total harmonic distortion < 15% with Power Factor > 0.95
  • Analog input dimming level control
  • Built-in 0-10V isolation transformer driver
  • Under 10% output ripple current
  • Wide dimming range from 1% to 100%
  • FlickerlessTM LED dimming technology
  • Quasi-resonant control to achieve high efficiency (typical > 85%)
  • Small size xx Two-stage topology enables small-size input and output filter capacitors xx 200kHz maximum switching frequ

iW3630 Applications

  • Dimmable LED ballast with analog input for dimming control
  • Dimmable LED ballast with 0-10V interface for dimming control
  • Output power up to 45W
