♠ TAS5612LA 125-W Stereo and 250-W Mono PurePath™ HD Digital-Input Class-D Power Stage
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 constantcurrent-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.
