6-LED Driver with PWM Dimming Interface
FAN5701 — Compact 6-LED Driver for Mobile Platforms March 2013 FAN5701 — Compact 6-LED Driver for Mobile Platforms Features Description The FAN5701 is a highly integrated and efficient charge- Six (6) Parallel LEDs (up to 30mA each) pump-based multi-LED driver. The device can drive up to six Total Package Load Current Capability: 180mA LEDs in parallel with a total output current of 180mA. Two Default Groups of Four (4) and Two (2) LEDs for The FAN5701 is capable of driving a primary display Main and Sub-Display Lighting with Individual PWM backlight requiring four to six LEDs. When more than four Dimming Controls that Operate up to 20kHz LEDs are needed for backlighting, the FAN5701’s two PWM dimming inputs can be connected together to provide the >600:1 Dimming Ratio for 100Hz PWM Frequency proper dimming control for all six LEDs. When a primary and Up to 92% Efficiency sub-display is needed, the FAN5701 can be controlled such that each group can be dimmed independently. For candy- Built-in 1.5x Charge Pump with Low-Dropout Bypass bar phones requiring a primary display and keypad lighting, Switch the FAN5701 offers a simple, and compact lighting solution. Wide Input Range: 2.7V to 5.5V Regulated internal current sinks deliver excellent current and V Over-Voltage and Short-Circuit Protection OUT brightness matching to all six LEDs. The device provides excellent efficiency without an inductor by operating the Over-Temperature Protection charge pump in 1.5x or pass-through modes. 1.2MHz Switching Frequency for Small-Sized The FAN5701 can be ordered with I values of 30mA, SET Capacitors 20mA, 15mA, or 8mA and available in WLCSP or ultra-thin 16-Bump 1.61mm x 1.61mm WLCSP (0.6mm Height) UMLP package types. The default I is always determined SET by the part number purchased (see Ordering Information) 16-Lead 3.0mm x 3.0mm UMLP (0.55mm Height) .
