The AL1663RS-13 from Diodes Incorporated is a high-performance, single-stage LED controller designed for dimmable LED lighting applications. It functions as a Flyback and Buck-Boost controller, utilizing primary side regulation (PSR) to achieve accurate constant current (CC) regulation without the need for opto-couplers or secondary control circuitry.
This controller operates in BCM mode and switches at the valley, contributing to good EMI performance and efficiency. It supports universal input voltage and achieves high power factor (PF) and low total harmonic distortion (THD) by operating in constant on-time mode. The AL1663RS-13 supports multiple dimming modes, including analog dimming (0.3V to 2.4V DC signal on APWM pin) and PWM dimming (digital signal on APWM pin). For PWM-to-DC dimming, a digital signal on the PWM D pin with a capacitor on the APWM pin is used.
Key features include low start-up and operating current, along with integrated protections such as Under Voltage Lock Out (UVLO), Output Over Voltage Protection (OVP), Output Short Protection (OSP), Over Current Protection (OCP), Thermal Fold-back Protection (TFP), and Over Temperature Protection (OTP). The device is supplied in an 8-SOIC package, suitable for surface mount applications.
Applications for the AL1663RS-13 include general LED lighting drivers with dimming functions, general-purpose constant current sources, and LED backlighting drivers.
