Diodes Incorporated introduced the AL1673. The AL1673 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 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 AL1673 features low start-up current and low operating current. It integrates multiple protection functions including overvoltage, short-circuit, overcurrent and over-temperature protection.
The AL1673 has a built-in 600 V/2 A high-voltage MOSFET and is available in SO-8EP package.
