Single Stage Dimmable Buck Converter with 600V/4A MOSFET
The AL1672 is a hig-hperformance single stage Buck convertor, targeting dimmable LED lighting applications. It operates 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 Diodes Advantage
The AL1672 is a high-performance single stage Buck converter
with built-in MOSFET for PWM/Analog dimming applications.
