SSMG501-20

Elektronische Bauelemente SSMG501 Series Low Power Constant Current LED Driver RoHS Compliant Product A suffix of “-C” specifies halogen or lead -free DESCRIPTION SSMG501 is a simple general purpose current regulation component that can be easily used in various LED lighting applications. With the excellent load/line regulation and minimized chip current skew, SSMG501 keep LED’s current very stable even when power or load fluctuate in a wide range and make intensity very uniform in large area of LED light source. Except power supply function, the VDD pin of SSMG501 is output enable (OE) also, and can be used in digital PWM controlled circuit to achieve more precise current adjusting in gray level applications. The minimized power supply voltage let SSMG501 be used as a current regulative diode (CRD) when VDD and VP pin are tight together. This application makes SSMG501 very easy to be used. Just like a diode, when this diode is inserted in LED series, the current in circuit is regulated. In high supply voltage and low LED load voltage application, two or more single channel SSMG501 can be connected in series to share redundant high voltage. the extra redundant voltage can be share by each SSMG501 by a reasonable mechanism. This special capability let SSMG501 very suit for the usage of wide range power supply that many liner type LED drivers cannot work.
