General Description
The GR6004 is a high efficiency constant current
driver for high brightness LED. The 0.2V reference
voltage minimized the power dissipation of the LED
current set resistor that located between FB to GND.
This low reference voltage increases the efficiency
apparently with the one LED load condition. Beside,
a

only
dissipated a little power in the conduction period. In
order to meet the mini size applications, the small
size inductor and output capacitor usually used
under the 750KHz operating. There are over-
temperature protection (OTP) and over-current
protection (OCP) in GR6004. These protection
functions could prevent GR6004 from damage in
abnormal situations.
