The LMZ10500 nano module is an easy-to-use step-down DC/DC design capable of driving up to 650-mA load in space-constrained applications. Only an input capacitor, an output capacitor, a small V CON filter capacitor, and two resistors are required for basic operation. The nano module comes in an 8-pin µSiP footprint package with an integrated inductor. Internal current limit based soft-start function, current overload protection, and thermal shutdown are also provided.

TIDA-010076 — Daisy-chained power and data over single pair Ethernet (T1) reference design

The TIDA-010076 shows the transfer of 220-W power and 100-Mbit/s data over SPE. Communication systems in daisy-chain topology need significantly less hardware and wiring than conventional systems in star-topology. When combined with single-pair Ethernet (SPE, 100BASE-T1) and power over data line, (...)
