AL1672 - SINGLE STAGE DIMMABLE BUCK CONVERTER

Description

The AL1672 is a high performance single stage Buck convertor, targeting dimmable LED lighting application.

It is operating at BCM mode which results in good EMI and efficiency.

The AL1672 can support multiple dimming modes.

Features

  • low start-up current and low operation current. It integrates multiple protections including over voltage, short circuit, over current and over temperature protection. It also integrates 600V/4A high voltage MOSFET. The AL1672 is available in SO-8EP package. Pin Assignments (Top View) CS 1 GND 2 EP DRAIN 3 DRAIN 4 SO-8EP 8 COMP 7 APWM 6 FB 5 VCC Features.

NOT RECOMMENDED FOR NEW DESIGN NO ALTERNATIVE PART AL1672 SINGLE STAGE DIMMABLE BUCK CONVERTER WITH 600V/4A MOSFET Description The AL1672 is a high performance single stage Buck convertor, targeting dimmable LED lighting application. It is operating at BCM mode which results in good EMI and efficiency. The AL1672 can support multiple dimming modes. When a 0.3~2.4V DC signal is applied on APWM pin, the device will operate in analog dimming mode. When a digital signal is applied on APWM pin, the device works at PWM dimming mode. The AL1672 features low start-up current and low operation current. It integrates multiple protections including over voltage, short circuit, over current and over temperature protection. It also integrates 600V/4A high voltage MOSFET.
