FAN5611/FAN5612/FAN5613/FAN5614
Low-Dropout LED Drivers for White, Blue or any
Color LED
Features
• LED Drivers for parallel-connected 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 2x2 MLP
Applications
• Cell Phones
• PDA, DSC, MP3 Players

• LCD Display Modules
• Keyboard Backlight
• LED Displays
General Description
The FAN5611/FAN5612/FAN5613/FAN5614 driver family
provides matched current source bias for white, blue or any
color LEDs. 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 FAN5611 and the FAN5613
are capable of driving four LEDs, while the FAN5612 can
drive three LEDs. The FAN5614 is designated to drive two
high current LEDs. In any case, at least I1 should be always
connected to an LED in order to have the other LEDs driven
with a matched current to I1.
The FAN5612, FAN5613 and FAN5614 have Enable pin.
When these devices are disabled, the supply current drops to
less than 1µA.
The FAN5611, FAN5612 and FAN5614 drivers are available
in a 6-lead SC-70 package. The FAN5613 is available in an
8-lead MLP package.
