Overview

NEW PRODUCT AL1666 HIGH PERFORMANCE DIMMABLE LED CONTROLLER Description The AL1666 is a high performance single stage Flyback and Buckboost controller, targeting dimmable LED lighting application.
It is a primary side regulation (PSR) controller which can provide accurate Constant Current (CC) regulation without opto-coupler and secondary control circuitry.
It is operating at BCM mode which results in good EMI and efficiency, and keeps high PF and low THD under universal input voltage.
The AL1666 can support analog/PWM dimming modes.
When a 0 to 2.
4V DC signal is applied on ADIM pin, the device will operate in analog dimming mode; when a digital signal is applied on PWMD pin and the ADIM p...
