Future Electronics Offers AC/DC Primary Side Controllers Simplifying LED Driver Design

Future Electronics, a global leading distributor of electronic components, announces immediate availability of NCL30080/1/2/3 primary side controllers which offer precise current regulation (±1% typical) across wide variation in line voltage and LED forward voltage, simplifying LED driver design.

The quasi-resonant operation ensures high efficiency, and a novel primary side control method eliminates the need for secondary side feedback circuitry, biasing and an optocoupler, saving board space and additional costs. Wide VCC input range and low start-up current requirements simplify biasing and enable fast start-up and allow one design to support more than a 2:1 range of LEDs with a single transformer, whether the design requires an isolated flyback or non-isolated buck-boost topology.

The devices, from ON Semiconductor, feature strong drive capability with integrated gate drive clamp and operate over a wide temperature range suitable for indoor as well as outdoor lighting products. The NCL30082 and NCL30083 incorporate user programmable temperature current foldback, allowing users to support long LED lamp warranty requirements by protecting the driver from potential overheating when installed in sealed fixtures. These devices also support 5 step log dimming which allows the lamp to be dimmed without the need for a specialized Triac dimmer switch.

Featuring precise current regulation, support for wide line variation and LED forward voltage, very efficient quasi-resonant control, step dimming options, user programmable feedback, along with a robust set of protection features, these AC/DC primary side controllers can be used for indoor lighting applications such as bulbs, lamps, wall sconces, under cabinet and down lights, as well as outdoor applications like step lights, accent lights, work and security lights.
