The DiodesZetex AL1666 is a high performance single stage Fly back and Buck boost controller, targeting dimmable LED lighting application. It is a primary side regulation (PSR) controller which can provide accurate Constant current (CC) regulation without opto-coupler and secondary control circuitry. It is operating at BCM mode which results in good EMI and efficiency, and keeps high PF and low THD under universal input voltage. The AL1666 has rich protection features. It integrates multiple protections including Under Voltage Lock Out (UVLO), Output over Voltage protection (OVP), Output Short Circuit protection (OSP), over current protection (OCP), Winding Short Circuit, Secondary Diode Short, Internal Thermal Fold-Back protection (TFP) and over temperature protection (OTP). The AL1666 is available in SO-8 (Standard) package.

Valley switching for low switching loss Support analog and PWM-to-DC dimming Analog/PWM-to-DC dimming range is 1% to 100% Tight CS Reference voltage 0.4V±1.5% high PF of more than 0.9 and low THD of less than 20%
