DescriptionThe 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.
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 simple keypad
lighting, the FAN5701 offers a simple and compact lighting
solution.
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.
The FAN5701 can be ordered with default ISET values of
30mA, 20mA, 15mA, or 8mA and available in WLCSP or
ultra-thin UMLP package types. The default ISET is always
determined by the part number purchased (see Ordering
Information).

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above
the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended
exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum
ratings are stress ratings only.

Note:
2. Junction-to-ambient thermal resistance is a function of application and board layout. This data is measured with four-layer
2s2p boards in accordance to JESD51- JEDEC standard. Special attention must be paid not to exceed junction
temperature TJ(max) at a given ambient temperate TA.
