YB1303 Datasheet | YOBON TECHNOLOGIES

Description The YB1303 provides a simple solution for driving three channels of any color LEDs with current matching ability. The ultra low dropout LED driver features higher peak efficiency and very low shutdown current. The LED current can be adjusted by an external resistor or the control voltage. The YB1303 can work independently or bine with any boost converters which need to have current matching function for LED drivers. The YB1303 is available in 6-pin tiny SC70-6 package. Features - LED Drivers for Parallel Connected - - - - - LEDs Only One External Resistor is Needed PWM and Analog Brightness Control No EMI and Switching Noise Power Saving Shutdown Mode (<0.1μA) Small Footprint SC70-6 Package Applications - LCD Display Modules - Keyboard Backlight - PDA, DSC, MP3 players - LED Displays - Handheld puters - Cell Phones Typical Application Circuit Figure 1: Typical Application Circuit YB1303 Rev.1.0 .yobon..tw Low Dropout LED Driver Pin Configuration CTR LED2 LED1 1 2 3 SC70-6 6 5 4 EN LED3 GND Figure 2: Pin Configuration Pin Assignment &Description Table 1 Pin 1 2 3 4 5 6 Name CTR LED2 LED1 GND LED3 EN Description Connect this pin with a resistor to set the LED current.
