SparkFun LED Driver Breakout - LP55231
BOB-13884 ROHS
DESCRIPTION DOCUMENTS
The SparkFun LP55231 LED Driver Breakout is a self-contained solution for
developing and deploying the nine-channel I C LED controller. Remarkably
simple, the breakout is equipped primarily with just the LP55231 LED controller
IC, plus three RGB LEDs. It also features pads and jumpers for replacing the
onboard LEDs with external ones, and configuring the I C bus, which allows you
to daisy-chain up to four LP55231s. This breakout drives the LEDs using Pulse
Width Modulation (PWM), so it is well-suited for variable intensity and color-
mixing applications!
Originally designed to be used in mobile device and automotive applications, it
isn’t meant to be overwhelmingly bright, and it has some unique qualities. First,
there is an onboard charge-pump power supply, which allows it to drive LEDs
with a forward voltage that’s higher than the power supply voltage. Second, the
LP55231 has an LED offload engine. This is an LED-specific microcontroller,
which allows it to perform LED operations without requiring assistance from the
host microcontroller. It can independently perform LED operations like chases,
blinks and fades.

In 2003, CU student Nate Seidle blew a power supply in his dorm room
and, in lieu of a way to order easy replacements, decided to start his
own company. Since then, SparkFun has been committed to sustainably
helping our world achieve electronics literacy from our headquarters in
Boulder, Colorado.
No matter your vision, SparkFun's products and resources are designed
