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 100m integrated power PMOSFET 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.
