MPQ7225
16-Channel Current Sink LED Driver with Adaptive Feedback Control (AFC),
AEC-Q100 Qualified
DESCRIPTION
The MPQ7225 is a 16-channel current sink LED driver. Each channel is rated for up to 200mA of current, and 16 ICs can be cascaded together to create a 256-channel solution.
The MPQ7225 is optimized for animated or dynamic lighting applications. It employs 12-bit pulse-width modulation (PWM) dimming and 6bit analog dimming register per channel, with individual control of each channel. The MPQ7225 is designed to function across distanced PCBs with a robust, high-speed, CANcompatible differential interface.
The MPQ7225 features adaptive feedback control (AFC) to maximize system efficiency. The output voltage of the pre-regulator (e.g.
