AL1665 Datasheet High Performance Dimmable Led Controller

Manufacturer: Diodes Incorporated

Overview: AL1665 HIGH PERFORMANCE DIMMABLE LED CONTROLLER.

General Description

The AL1665 is a high-performance single-stage flyback and buckboost controller, targeting dimmable LED lighting application.

It is a primary side regulation (PSR) controller that can provide accurate constant current (CC) regulation without optocoupler and secondary control circuitry.

It can be operated at BCM mode, which results in low EMI and high efficiency, and keeps high power factor (PF) and low total harmonic distortion (THD) under universal input voltage.

Key Features

  • It integrates multiple protections including undervoltage lockout (UVLO), output overvoltage (OVP), output short circuit (OSP), overcurrent protection (OCP), winding short circuit, secondary diode short, internal thermal foldback (TFP), and overtemperature protection (OTP). The AL1665 is available in SO-8 (Standard) package. Pin Assignments (Top View) ADIM 1 NTC/PWM 2 COMP 3 CS 4 8 FB 7 VCC 6 OUT 5 GND SO-8 (Standard) Features.
