Diodes Incorporated AL1665 is a universal high-current precision, single-stage fly back and buck-boost controller. It uses the primary side regulation (PSR) control method, which can provide accurate constant current (CC) regulation without optocoupler and secondary control circuitry. It operates at BCM mode and keeps beneficial EMI and efficiency. It also keeps high PF and low THD over wide input-voltage. The AL1665 supports 0 V to 10 V analog dimming applications and direct PWM dimming and 0 V to 2.5 V analog dimming modes. The AL1665 features low startup current and low operation-current. AL1665 integrates full protection function and makes the LED driver more reliable. It is available in SO-8 packaging.
