FAN5616  
High-Efficiency, Constant-Current LED Driver with  
Adaptive Charge Pump  
Features  
Description  
3-Channel Parallel LED Driver for a Large Range of  
The FAN5616 generates a regulated output current from  
a battery with an input voltage between 2.7V to 5.5V.  
Switch reconfiguration and fractional switching tech-  
niques are utilized to achieve high efficiency over the  
entire input voltage range. The adaptive nature of the  
built-in charge pump eliminates the need for LED pre-  
selection (matching) and ensures operation with high  
efficiency. The driver's built-in, proprietary, auto-sense  
circuitry ensures the same high efficiency regardless of  
the number of LEDs. When the input voltage is suffi-  
ciently high to sustain the LED’s programmed current  
level, the FAN5616 reconfigures itself to operate as a lin-  
ear regulator, and the charge pump is turned off.

Up to 90% Efficiency  
Up to 50kHz PWM Dimming Frequency  
Low EMI, Low Ripple  
Up to 120mA Output Current  
Drives up to 3 LEDs at 40mA each  
The FAN5616 supports both digital and PWM LED  
brightness control methods. The built-in 2-bit DAC offers  
a selection of four LED current levels, each level is a per-  
centage of the maximum LED current set by the external

Built-in 2-bit DAC to Control LED Current in Digital  
The FAN5616 includes built-in shutdown, short circuit  
and thermal protection circuitry. A built-in smart soft-start  
circuitry prevents excessive current draw during power  
on while allowing for an increased PWM frequency for  
dimming.

Minimal external components are required. Only two  
0.1µF to 1µF bucket capacitors, a 4.7µF input capacitor  
and a 1µF output capacitor are needed for proper opera-  
tion.
