Low-Dropout LED Drivers for White, Blue,
or any Color LED Features Description ■ LED drivers for parallel-connected LEDs (2 to 4) 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. ■ Ultra-low voltage drop (< 300mV) to support direct Li-ion applications
■ No EMI, no switching noise
■ No external components needed for current matching
■ Both analog and PWM brightness control
■ FAN5611, FAN5613 feature up to 160mA bias current (up to 40mA for each LED)
■ FAN5612 features up to 120mA bias current (up to 40mA for each LED)
■ FAN5614 features up to 160mA bias current (up to 80mA for each LED)
■ Enable/Shutdown control (FAN5612, FAN5613,
FAN5614)
■ Shutdown current < 1μA
■ Small footprint SC-70 and MLP The FAN5612/13 and 14 are selected using an ENABLE …
