Input: 6 - 30v DC to 50kHz
Output: 2 - 25VDC @820ma
Constant current: 820mA +/−5%
Size: 35mm x 18mm x 12mm
Two wires at the output LED: - Red(Pink) +; White is -
Driver is Step-down, means the LED voltage should be lower than driver supply voltage.
eg: input: 12V - LED combination up to 10V;
if input is 24V - LED combinations up to 22V
If you want to know more about this LED driver:
Fast Schottky SS14 diode rectifiers are used. Very low drop loss and better efficiency.
Input capacitor is Low ESR. Capacitor life will be longer, compared to normal one. Combined with the schottky rectifier you can use it quite efficient with from DC up to 50khz from electronic transformer
According the datasheet, this chip is power enough to handle even 1.2A . If you are good in electronics, you can easily modify the output current up to 1.2A with adding SMD resistor, parallel to the 0.2ohm and 0.3ohm resistors.
The inductor is big enough to handle the LED power, and to help the IC working more efficient from 6 to 30V input.
