GR8210

Universal and Dimmable LED Driver

Features

ꢀ

General Description

Input voltage range from 5V to 450V

The GR8210 is a high brightness LED driver with

the cascode topology that patented by Grenergy. A

high voltage power NMOSFET, BV_DSSis 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 GR8210 and the input voltage

rail respectively to absorb the very large voltage

potential. The current peak value was decided by

the sensing resistor in the CS pin, the low side

device was turned off by the current peak detection

then delay a fixed off time that set by the resistor in

the RT pin of GR8210.

ꢀ

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

Application

ꢀ

DC/DC or AC/DC LED driver application

LED T-bar lighting

There are PWM and liner dimming in GR8210 to

adjust the LED brightness. In the abnormal

operation, the inner OTP function could protect the

IC damage.

Cabin light in car

Both non-isolation and isolation lighting in high

input voltage

* Refer to Feature List on page 2 for the switching dimming

function
