MAXREFDES1132: 2W DC-DC flyback converter using MAX17596

The MAX17596 is a peak-current-mode controller for designing wide input-voltage flyback regulators. The device offers input thresholds suitable for low-voltage DC-DC applications (4.5V to 36V) and contains a built-in gate driver for an external n-channel MOSFET.

24VDC Input (Dual Automotive Batteries) Automotive Multi-Phase Synchronous Buck Reference Design

This efficient, high-power reference design uses the LM5119 dual-phase synchronous buck controller to regulate 14.4V at 60A. This design can be used to feed a single vehicle battery source from a dual-battery system commonly found in trucks. Features include input EMI filtering, output hot-swap protection, input/output current monitoring, and temperature monitoring.

Portable information board

"Portable information board", as the name suggests, displays the information you want to display on a device (screen) that you carry with you. The inspiration for this idea was that I met many elderly people who were lost before, but some of them were too old, had poor memory, forgot where their home was, couldn’t find their family members’ phone numbers, etc. (Although there are only a few, they are still exists, and China’s population is aging increasingly, so the proportion will inevitably increase).

Create a 1-Wire® Master with Xilinx PicoBlaze

Designers who must interface 1-Wire® temperature sensors with Xilinx field-programmable gate arrays (FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable software mentioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The system implements a 1-Wire master connected to a UART and outputs temperature to a PC from the DS28EA00 temperature sensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDs.
