FAN5701 — Compact 6-LED Driver for Mobile Platforms

Features

Description

The FAN5701 is a highly integrated and efficient charge-

pump-based multi-LED driver. The device can drive up to six

LEDs in parallel with a total output current of 180mA.

Six (6) Parallel LEDs (up to 30mA each)

Total Package Load Current Capability: 180mA

Two Default Groups of Four (4) and Two (2) LEDs for

Main and Sub-Display Lighting with Individual PWM

Dimming Controls that Operate up to 20kHz

The FAN5701 is capable of driving a primary display

backlight requiring four to six LEDs. When more than four

LEDs are needed for backlighting, the FAN5701’s two PWM

dimming inputs can be connected together to provide the

proper dimming control for all six LEDs. When a primary and

sub-display is needed, the FAN5701 can be controlled such

that each group can be dimmed independently. For candy-

bar phones requiring a primary display and keypad lighting,

the FAN5701 offers a simple, and compact lighting solution.

>600:1 Dimming Ratio for 100Hz PWM Frequency

Up to 92% Efficiency

Built-in 1.5x Charge Pump with Low-Dropout Bypass

Switch

Wide Input Range: 2.7V to 5.5V

Regulated internal current sinks deliver excellent current and

brightness matching to all six LEDs. The device provides

excellent efficiency without an inductor by operating the

charge pump in 1.5x or pass-through modes.

V_OUTOver-Voltage and Short-Circuit Protection

Over-Temperature Protection

1.2MHz Switching Frequency for Small-Sized

Capacitors

The FAN5701 can be ordered with I_SETvalues of 30mA,

20mA, 15mA, or 8mA and available in WLCSP or ultra-thin

UMLP package types. The default I_SETis always determined

by the part number purchased (see Ordering Information)
