The AL1672-40CSP-13 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 AL1672-40CSP-13 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 AL1672-40CSP-13 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 AL1672-40CSP-13 is available in SO-8EP package.
