Description

In many human-machine interface (HMI) applications, efficient and high-performance LED response effects, such as blinking, breathing, and chasing, are crucial to improving the end-user experience.

The LP5036RJVR is a constant-current-sink LED driver with 30 or 36 channels. To enable spectacular LED effects with zero audible noise, the LP5036RJVR contains a 29 kHz, 12-bit PWM generator for each channel, as well as channel/module independent color mixing and intensity control, formerly known as brightness control registers. Users will love the device's ultra-low shutdown Iq Power Saving Mode, while designers will appreciate the LP5036RJVR's three programmable R G B banks' incredibly simple software coding.
