AL1666 Datasheet High Performance Dimmable Led Controller

Manufacturer: Diodes Incorporated

Overview: NEW PRODUCT AL1666 HIGH PERFORMANCE DIMMABLE LED CONTROLLER.

General 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.

Key Features

  • It integrates multiple protections including Under Voltage Lock Out (UVLO), Output Over Voltage Protection (OVP), Output Short Circuit Protection (OSP), Over Current Protection (OCP), Winding Short Circuit, Secondary Diode Short, Internal Thermal Fold-Back Protection (TFP) and Over Temperature Protection (OTP). The AL1666 is available in SO-8 (Standard) package. Features.
  • Primary Side Regulation without Opto-Coupler.
  • Valley Switching for Low Switching Loss.
  • Support Analog and PWM.
