iW3630
AC/DC Digital Power Controller for High Power Factor Analog and 0-10V Dimmable LED Drivers
1 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 has a built-in 0-10V dimming interface that works directly with 0-10V dimming systems, eliminating the need for a driver circuit and microcontroller. It also provides a PWM digital interface to support wireless SSL applications, without adding auxiliary power supplies. The iW3630 uses Dialog’s unique digital FlickerlessTM technology to eliminate visible flicker in the entire dimming range and to minimize low frequency output ripple current.
