General Description

The AL58263 is a 16-channel constant-current LED driver with 16-bit grayscale Adaptive Pulse Density Modulation (APDM) and supports error diagnostics, power-saving functionality, and current gain control.

This distinctive APDM technology abates the non-ideal IOUT distortion due to non-symmetric transient responses and enhances the refresh rate by efficiently separating the frame waveform.

Pin Assignments (3D Photo – Not to Scale) The device operates over a 3V to 5.5V input voltage range, 15V output channel voltage, fast 25MHz DCK input, and delivers up to 55mA of high-accuracy current to each LED string.
