FAN5611/FAN5612/FAN5613/FAN5614 Low-Dropout LED Drivers for White, Blue, or any Color LED

Features
LED drivers for parallel-connected LEDs (2 to 4) Ultra-low voltage drop ( 300mV) to support direct

Description
The FAN5611/12/13/14 low-dropout product family is designed to drive two to four parallel LEDs, providing matched current source bias for all color LEDs. The LED current is set by an external resistor, RSET. The FAN5611/13 supports four parallel LEDs with up to 160mA bias current (up to 40mA per output). The FAN5612 supports three LEDs with up to 120mA bias current (40mA per output). The FAN5614 drives two high-current LEDs (80mA per output). Pin I1 should always be connected to an LED to provide a matched current for any additional LEDs. The FAN5612/13 and 14 are selected using an ENABLE pin. When the chip is not selected (ENABLE pin is LOW), the supply current drops to less than 1 A. The FAN5611, FAN5612, and FAN5614 are available in an SC-70 package. The FAN5611 and FAN5613 are available in MLP packages.
