Preliminary Datasheet High Efficiency Step Down LED Driver SM8200 GENERAL DESCRIPTION The SM8200 is a High efficiency step-down LED Driver, It has very wide input voltage range from 8V to 48V, The device is designed to operate in critical conduction mode (CrM) control scheme (This operating mode results in an average LED current which is equal to half of the peak switching current) optimized to drive high current LEDs. Thus highly efficient and accurate LED current regulation can be achieved. In CrM, the switching frequency will vary with line, load , inductance and switching loss, the current of the inductor starts at zero each switching cycle. So, external power MOSFET can significantly be reduced the peak spike voltage.
