    • Evaluation Board for NCL30082 - Flyback 10 W / 500 mA Current Mode Controller

    Overview

    The NCL30082 is a PWM current mode controller targeting isolated flyback and non-isolated constant current topologies. The controller operates in a quasi-resonant mode to provide high efficiency. Thanks to a novel control method, the device is able to precisely regulate a constant LED current from the primary side.

    This removes the need for secondary side feedback circuitry, biasing and an optocoupler. The device is highly integrated with a minimum number of external components. A robust suite of safety protection is built in to simplify the design. The device supports analog/digital dimming and thermal foldback. While the NCL30082 has integrated fixed overvoltage protection, the designer has the option to program a lower OVP level.

    Key Applications: Integral LED Drive Electronics
