SLM2861LED constant current drive module

In order to provide low cost constant current drive module to solar garden lights and high-power solar street lamps, Shanghai dragon microelectronics company recently launched a buck type high-power constant current drive module SLM2861. It can be driven when the input voltage of 3 24V, each string of 6 watts of LED, or drive a string of 6 watts of LED, with a total output power of up to 18W 3. When the input voltage is 32V, it can drive a string of 8 watts of LED, the total output power of up to 24W. Because it works in the state of buck, so it is very efficient, when the ratio is relatively small, the maximum efficiency of up to 95%. Its external circuit is very simple, only a resistor, a capacitor, an inductor and a diode.
