The project is a cube shaped 10x10x10 LED matrix controlled by a serial interface.
The MAX15112 high-efficiency, current-mode step-down regulator with integrated power switches operates from 2.7V to 5.5V and delivers up to 12A of output current in a small 2mm x 3mm package. The MAX15112 offers excellent efficiency with skip mode capability at lightload conditions, yet provides unmatched efficiency under heavy load conditions.
The MAXREFDES1131 provides the internal core voltage (VCCINT) for Xilinx Ultrascale+ FPGAs. This reference design targets FPGAs with a -2L speed grade that require 0.72V for VCCINT from a 12V intermediary bus. The converter supports a maximum load of 12A at a 400kHz switching frequency.
This 45W Type-C PPS reference design uses Infineon's EZ-PD™ PAG1s and PAG1P controllers and CoolGaN™ 600V GIT HEMT. The solution complies with international energy efficiency standards including DoE Level 6/CoC Level 2, and its standby power can be as low as less than 30 mW. The solution is tested to CE standards defined by CISPR32 Class B and achieves a high board-side power density of 17.71 W/in3. This solution is designed for use with USB PD (including PPS), QC power adapters. Adapters covering traditional charging protocols including Apple Charging, BC1.2, QC 3.0 and Samsung AFC are also supported. PAG1S and PAG1P jointly provide low BOM cost, high-performance solutions compatible with PD/PPS/QC.

Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity. The MAX17690 eliminates the need for an optocoupler or auxiliary transformer winding and achieves ±5% output voltage regulation over line, load, and temperature variations.

The MAX17595 is a peak-current-mode controller for designing wide input-voltage flyback regulators. The MAX17595 offers optimized input thresholds for universal input AC-DC converters and telecom DC-DC (36V to 72V input range) power supplies. It contains a built-in gate driver for an external n-channel MOSFET. The MAX17595 houses an internal error amplifier with 1% accurate reference, eliminating the need for an external reference.
