5-channel (3 +V and 2 -V) hot-swap reference design

This article presents a five-channel hot-swap circuit that handles both positive and negative input voltages with sequential turn-on. The unique configuration allows two negative-voltage channels not protected by circuit breakers, in addition to three positive-voltage channels, to be controlled by a single MAX5927A positive-voltage hot-swap controller. The included test data verifies that the circuit meets the described load and power-sequencing requirements of the five channels.

Complete solution for low-cost electrical equipment including 12V buck converter

The MAX5953A provides a simple and inexpensive, yet complete, nonisolated power solution for a powered device (PD) in a Power-over-Ethernet (PoE) system. The circuit provides the PD with detection and classification signatures in compliance with the IEEE^SM 802.3af standard, plus programmable inrush-current control, an integrated power switch, a PWM controller, and integrated high- and low-side switches. The buck step-down converter is capable of > 80% conversion efficiency while delivering 12V at 0.85A.
