GPLD80B 0mA High Efficiency StepUP LED Driver Features RoHScompliant "x" case Package Power LED Driver Constant Current Output (±% Output Current Accuracy) LED Driver Rated Current 0mA Soft Start

1 GPLD80B 0mA High Efficiency StepUP LED Driver Features RoHScompliant "x" case Package Power LED Driver Constant Current Output (±% Output Current Accuracy) LED Driver Rated Current 0mA Soft Start Wide Input Voltage Range:9V to V (8V for 0.sec.) Output Power to.8w Driver LED Strings of up to 8V (V to 8V) High Efficiency (up to 9%) PWM/Digital Dimming and Analog Voltage Dimming Open Voltage Protection / Short LED Protection 0 C ~ 8 C Operation Temperature Range GPLD80B Application V and V Solar Lighting Systems Household/Commercial Lighting Suitable for High illumination LED Power Limited (battery) Lighting System GPLD80B is a high efficiency stepup converter optimized to drive high current LEDs. The control algorithm allows highly efficient and accurate LED current regulation. The device operates from an input 9Vdc to Vdc and provides an externally adjustable output current of up to 0mA and output power up to.8 watts. Compact size of "x" case allows designer to integrate this driver together with LED module. UL9V0 grade molded case with high grade filling material provide excellent fire proof characteristics.

The advantage of such approach is to reduce the EMI.
