ON Semiconductor Introduces New Energy-Efficient Controller Solution for LED Lighting

Constant-current and constant-voltage IC solutions enable precise wide-range dimming for modern LED lighting

ON Semiconductor (Nasdaq: ON) launched two new LED lighting controller solutions. The dimmable NCL30386 and non-dimmable NCL30388 provide market-leading choices for designers of LED lighting devices such as lamps for offices and industrial buildings.

Both devices are high power factor (PF), single-segment, constant-current (CC), and constant-voltage (CV) for flyback, buck-boost or single-ended primary-inductor converter (SEPIC) power topologies. Primary-side regulation (PSR) pulse width modulation (PWM) controller. They use quasi-resonant (QR) mode of operation, energy efficiency levels exceed the EU's Ecodesign, the United States Energy Star (ENERGY STAR®) and NEMA SSL and other energy standards.

The integrated high-voltage start-up current source ensures fast startup, low standby energy consumption, and wide-range output operation.

These devices are simple to use and operate over a wide voltage (VCC) range of 9.2 - 26 VDC. They feature valley-locking and frequency reversal to ensure high energy efficiency over the entire voltage range. It further simplifies the design of LED lighting applications by including safety functions such as undervoltage and overvoltage protection, as well as detecting short circuits in the output, windings, and diodes.

Both the NCL30386 and NCL30388 do not require many external components to complete the design, reducing time-to-market, bill of materials (BoM) costs, and reducing the space required to implement a complete lighting solution.

In addition, the NCL30386 offers excellent dimming capabilities, including linear or quadratic dimming curve options.

Ryan Zahn, Marketing and Application Director of ON Semiconductor's AC-DC Business Unit, said: "Because of the low energy consumption certification of LED lighting, its energy-efficient work is a management cost to cope with rising energy prices and environmental protection factors. Our new program not only provides The leading energy efficiency of the market also provides designers with a high degree of flexibility and can meet and exceed current energy efficiency standards.The wide range of new devices, low standby power consumption and fast start-up allow designers to simplify their work. In addition, the NCL30386 offers a wide range of very precise dimming controls and is the ideal solution for smart lighting."
