1 / 9 page 1 Date: 6/30/04 SP7611A/7612/7614 Low Dropout LED Driver for Any Color LED © Copyright 2004 Sipex Corporation FEATURES ■ LED Drivers for parallel connected LEDs ■ Ultra Low Dropout Voltage of 150mV (SP7614) ■ No EMI, no switching noise ■ Integrated current matching ■ PWM and Analog brightness control ■ Enable/Shutdown control ■ Shutdown current < 1µA ■ Small footprint SC-70 Package Low Dropout LED Driver for any Color LED ® APPLICATIONS ■ Next Generation Mobile Phones ■ PDA, DSC, MP3 players ■ Handheld Computers ■ LCD Display Modules ■ Keyboard Backlight ■ LED Displays TYPICAL APPLICATION SCHEMATIC DESCRIPTION The SP761X driver family provides a simple solution for a matched current source any color LED. The current in the LEDs can be programmed by an external resistor. The Individual LED currents are 200 x ISET, where ISET is the current through the external resistor connected to the CTRL pin. The SP7611A is capable of driving four LEDs, while the SP7612 can drive three LEDs. The SP7614 is designated to drive two high current LEDs. LED1 should always be connected to an LED in order to have the other LEDs driven with a matched current to LED1. The SP7612 and SP7614 have Enable pins. When these devices are disabled, the supply current drops to 0.01µA typical. The SP7611A, SP7612 and SP7614 drivers are available in a small footprint 6-pin SC-70 package.
