NEW PRODUCT AL1663/AL1663R UNIVERSAL FLYBACK AND BUCK-BOOST SINGLE STAGE DIMMABLE LED CONTROLLER Description The AL1663/AL1663R is a high performance single stage Flyback 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 optocoupler and secondary control circuitry. It is operating at BCM mode which results in good EMI and efficiency, and keeps high PF and low total harmonic distortion (THD) under universal input voltage. The AL1663/AL1663R can support multiple dimming modes. When a 0.3 to 2.4V DC signal is applied on APWM pin, the device will operate in analog dimming mode.
