Small LCD screen backlighting charge
pump LED drivers
Description
The AP3154A and AP3156
are charge pump LED drivers
for small LCD screen
backlighting. They are well
suited for LCD screens less
than 3”.
Both use a tri‐mode charge
pump switch (1X), fractional
(1.5X), and doubling (2X)
conversion to maximize
efficiency in white LED
applications.
A low external parts count
(two 1μF flying and two
small 1μF capacitors at VIN
and VOUT) make them ideally
suited for small, battery‐
powered applications.
The Diodes advantage
The AP3154A and AP3156 provide a simple cost effective solution for
small screen LCD backlighting
x1/x1.5/x2 tri-mode voltage conversion
Increases efficiency giving longer battery life.
No inductor, diodes
Reduces EMI and reduces PCB area
A serial digital interface is
used to enable, disable and
set current for each LED with
a 32‐level logarithmic scale
plus four low‐current
settings down to 50μA for
SDI digital interface
Versatile control to program LED current with 16-level/32-level
logarithmic scale
Small footprint low profile packages
Reduces PCB area and height restrictions
Soft-start & Soft-stop
Reduces In-rush current during start up and power down.
