FAN5607  
LED Driver with Adaptive Charge Pump DC/DC  
Converter  
Features  
Description  
• Parallel LED Driver Supports all Forward Voltages  
• Adaptive VOUT Adjustment to the Highest Diode Voltage  
• Internally Matched LED Current Sources  
• Built-in Charge Pump has Three Modes of Operation:  
– 1X, 1.5X, and 2X Mode  
The FAN5607 generates regulated output current from a bat-  
tery with input voltage varying between 2.7V to 5.5V.  
Switch reconfiguration and fractional switching techniques  
are utilized to achieve high efficiency over the entire input  
voltage range. A proprietary internal circuitry continuously  
monitors each LED current loop and automatically adjusts  
the generated output DC voltage to the lowest minimum  
value required by the LED having the highest forward volt-  
age. This adaptive nature of the FAN5607 eliminates the  
need for LED pre-selection (matching) and ensures opera-  
tion at high efficiency. When the input voltage is sufficiently  
high to sustain the programmed current level in the LEDs,  
the FAN5607 re-configures itself to operate as a linear regu-  
lator, and the DC-DC converter is turned off. Only two 0.1µF  
to 1µF bucket capacitors and two 4.7µF input/output capaci-  
tors are needed for proper operation. LED current can be  
programmed using an external resistor. The resistor sets the  
maximum LED current and a PWM signal applied to the  
enable pin can modulate that current level between 0mA  
(off) and the maximum level.  
• Up to 93% Efficiency  
• Low EMI, Low Ripple  
• Up to 120mA Output Current (4 × 30mA )  
• External Resistor to Set Maximum (100%) LED Current  
• Enable Input Can be Duty-Cycle-Modulated to Control  
LED Current Level Between 0 and 100%  
• 2.4V to 5.5V Input Voltage Range  
• ICC < 1µA in Shutdown Mode  
• 1MHz Operating Frequency  
• Shutdown Isolates Output from Input  
• Soft-Start Limits Inrush Current  
• Short Circuit Protection  
• Minimal External Components Needed  
• Available in a 4x4mm 16-lead MLP Package  
Applications  
• Cell Phones  
Soft-start circuitry prevents excessive current draw during  
power on. The device has built-in short circuit protection.  
• Handheld Computers  
• PDA, DSC, MP3 Players  
• Keyboard Backlight  
• LED Displays  
The device is available in 4x4mm 16-lead MLP package.
