3 Description
Efficient and high-performance LED response effects,
such as blinking, breathing, and chasing, are critical
to improving end-user experience in many human
machine interface (HMI) applications.
The LP503x device is a 30- or 36-channel constant-
current-sink LED driver. The LP503x has a 29 kHz,
12-Bit PWM generator for each channel, as well as
channel/module independent color mixing and
intensity control, formerly called brightness control
registers to enable vivid LED effects with zero audible
noise. Users can benefit from the device’s ultra-low
shutdown Iq Power Saving Mode, while designers will
appreciate the incredibly straightforward software
coding of the LP503x’s three programmable R G B
banks.
