Solution for LED power supply within 25W and cost within 2 yuan


Within 25W of LED power supply, the true era of 2 yuan has arrived, replacing the previous resistor capacitor voltage reduction scheme with the highest cost-effectiveness scheme. DU8612 is a product that integrates 500V high-voltage MOS. Packaging form SO8. The DU8612 has only 9 peripheral devices, and it also features advanced dynamic temperature control technology and an added output overvoltage protection function.




1、 Features:

1. Simple structure, efficiency over 90%, PF ≥ 0.5;


2. Similar products with built-in OVP protection (with no-load voltage limiting function).

3. Built in dynamic temperature control technology. Ensure the maximum output power of the product while fully ensuring its reliability.

4. Built in line voltage compensation, higher constant current accuracy and mass production consistency, output current accuracy ≤ 1%.

5. Higher integration, with only 9 components in the entire power supply, making it the product with the least peripheral components in the industry.

6. Compared to the BP series products, there are fewer peripheral components (integrated with DS capacitors and resistors. Reduced LN to ground resistance and capacitance, reduced VCC to ground resistance and LN, approximately 0.13 yuan cheaper). Resolved the issue of power off flashing. Low power consumption for short-circuit protection.

7. The total BOM cost of the power supply is only about 1.5RMB, making it the best choice for replacing resistance capacitance and voltage reduction.




2、 Application: 1. Input Vin=160V-265V, output 120V, 150mA.


2. Input Vin=200-265V, output 180V, 90mA, efficiency 92%
