The AL1666S-13 from Diodes Incorporated is a high-performance, single-stage Flyback and Buck-Boost controller designed for dimmable LED lighting applications. It operates as a primary side regulation (PSR) controller, providing accurate constant current (CC) regulation without the need for an opto-coupler or secondary control circuitry.
This controller supports both analog and PWM dimming modes, offering a dimming range from 1% to 100%. It operates in BCM mode, contributing to good EMI and efficiency, while maintaining high power factor (PF > 0.9) and low total harmonic distortion (THD < 20%) under universal input voltage. The AL1666S-13 integrates multiple protection features, including UVLO, OVP, OSP, OCP, winding short circuit, secondary diode short, internal thermal fold-back protection (TFP), and over-temperature protection (OTP).
The device is available in a standard 8-SO package and is suitable for general LED lighting drivers, 0 to 10V dimming luminaires, and general-purpose constant current sources. It offers tight LED current regulation with line regulation of ±2% (90VAC to 305VAC) and load regulation of ±2% (Full Load to Half Load).
Key electrical specifications include a voltage of 8.5V and a frequency of 150kHz. The operating temperature range is -40°C to 105°C (TA). The AL1666S-13 is designed for surface mount applications.
