Overview

GR8210 Universal and Dimmable LED Driver Features Input voltage range from 5V to 450V Cascode topology for lower switching loss and surge voltage Constant off time control Line compensation of output current Enable pin Switch/PWM/Linear dimming function Leading-edge blanking Frequency modulation in short circuit protection and low output voltage condition Over-temperature protection Over-current protection SOP-8 package, with few external components needed General Description The GR8210 is a high brightness LED driver with the cascode topology that patented by Grenergy.
A high voltage power NMOSFET, BVDSS is 600V, as the high side device and the power NMOSFET inside the GR8210 as the low side device in this cascode topology.
A Zener voltage, was generated by ST pin of the GR8210, turn on the high side device all the time by connected to the gate terminal of the high side device.
The source terminal and the drain terminal of the high side device are connected to the DRN pin of the GR82...
