The main push sd6602d/sd6603d/sd6604d is a high-precision, low-cost primary feedback LED constant current drive chip, should be

For flyback isolation LED illumination.

The chip works in the inductive current discontinuity mode, which is suitable for 90vac~265vac input voltage,

Output power below 18W.

The main push sd6602d/sd6603d/sd6604d uses the unique constant current control mode, the current accuracy reaches ± 3% within, and can pass

The over-peak current sampling resistor sets the output current. The 600V Power MOS switch is integrated inside the chip,

Using the original side feedback control mode, no loop compensation, no optocoupler, TL431, transformer auxiliary winding, etc.

dip-7-300-2.54

components, saving the system cost and volume.

Integrated in-chip led open/short circuit protection, primary side overcurrent protection, overvoltage protection, overtemperature protection

And so on to improve the reliability of the system.

The main push sd6602d/sd6603d/sd6604d is packaged in dip-7-300-2.54.
