Manufacturer: Diodes Incorporated

Overview: NEW PRODUCT AL1666A HIGH PERFORMANCE DIMMABLE LED CONTROLLER.

General Description

The DIODESTM AL1666A is a high performance single stage Flyback and Buck-boost controller, targeting dimmable LED lighting application.

It is a primary side regulation (PSR) controller which can provide accurate Constant Current (CC) regulation without optocoupler 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 AL1666A is available in SO-8 (Standard) package. Features.
  • Primary Side Regulation without Opto-Coupler.
  • Valley Switching for Low Switching Loss.
  • Support Analog and PW.
