GR6004

Constant Current Switching Converter for High Brightness

LED Driving

Features

General Description

ꢀ

Wide input voltage range from 4.5V to 26V

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,

Maximum efficiency over 95%

1.5A output current for HB LED

0.2V reference voltage for high efficiency

100mΩ integrated power PMOSFET

Built-in soft start

750KHz fixed switching frequency

Over-current protection

100mΩ 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.

Over-temperature protection

Lead free and green devices available

Application

ꢀ

MR16 LED lamp

Luminance applications with DC input voltage

LED flashlight
