Dimmable LED driver

15 November 2017 Opto-Electronics Power Electronics / Power Management

The AL1673 from Diodes Incorporated is a high-performance, single-stage LED driver-converter operating in flyback and buck-boost topologies, targeting dimmable LED lighting applications. It operates in BCM mode which results in good EMI and efficiency.

The AL1673 supports multiple dimming modes. When a 0,3–2,4 V d.c. signal is applied on the APWM pin, the device will operate in analog dimming mode. When a digital signal is applied on that pin, the device works in PWM dimming mode.

The AL1673 features low startup current and low operating current. It integrates multiple protection functions including over-voltage, short circuit, over-current and over-temperature protection. The AL1673 has a built-in 600 V/2 A high-voltage MOSFET and is available in an SO-8EP package.
