The MAX25630 is a 4x24-channel modular matrix driver. The integrated current outputs can sink up to 72mA LED current each. The source drive pins provide current to the columns of the matrix on a multiplexed basis. Device power comes from an external 3.3V or 5V supply, while the LED current-sink outputs can operate at up to 14V.

A feedback output pin (FB) is provided to control an external DC-DC converter so that voltage headroom can be optimized and the overall system power dissipation reduced.

The device is highly flexible due to its programmability using the UART interface. The interface allows the control of up to 16 devices in a star configuration. Among the programmable parameters are the LED current, individual PWM settings, and multiplex ratio.

The MAX25630 is available in TQFN and TSSOP packages and operates in the -40°C to +125°C temperature range.
