Dalian Dapinjia Group Launches Low-Cost Thyristor Dimming LED Solution Based on Microchip Technology and Products

On May 5, 2016, Dalian United Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its product is based on Microchip's PIC12HV752-based single-stage PFC thyristor dimming LED solution. With a small amount of program code, you can use the peripheral module (CIP) of the opposite core that comes with its MCU.

SCR is a semiconductor device that has emerged in recent years. It combines with LED lighting technology with its high efficiency and long life. It uses thyristor dimming to dim the LED replacement lamp. The existing dimmer circuit No change is possible, so thyristor dimming is increasingly recognized by the market. Dalian Dapin has launched a low-cost thyristor dimming LED solution based on Microchip technology and products to meet market demand.

Program features:

? Isolated output is safe and reliable;

? Continuous current mode CCM to ensure switching loss of low-side MOS;

High PF value reduces ballast losses;

? Less peripheral components, lower cost, suitable for small volume requirements;

• Full-bridge rectification requires only small, inexpensive film capacitors to replace bulky and expensive high-voltage electrolytic capacitors.

The solution's input voltage range is AC IN 90-240 V and the maximum output is 20Vdc/325ma. Its PF value is 0.95, which is equivalent to pure resistance, and its characteristics are similar to incandescent lamps. It can be applied to constant voltage and constant current with communication dimming or thyristor LED dimming power supply.
