PMBus multiphase power solution

MOS power IC full range

SMD aluminum electrolytic capacitor

KKST patch plug-in active passive crystal oscillator hot sale 24.576000MHZ

Summary:

Complete PMBus solution (from input protection and control to multi-phase power conversion). PMBus compatibility provides customers with input power health information and configurable protection, while power communication is configured and monitored.

The main features of the solution:

1.LM5066/LM25066 - Combines a high performance hot swap controller with a PMBus® compliant SMBus / I2C interface

- Accurately measure, protect and control the electrical operating conditions of the system connected to the backplane power bus.
- Continuously provide real-time power, voltage, current, temperature and fault data to the system management host via the SMBus interface.

2.UCD9224 - Multi-Track, Multi-Phase Synchronous Step-Down Digital Pulse Width Modulation (PWM) Controller Designed for Non-Isolated DC/DC Power Applications

- Integrated dedicated circuitry for DC/DC loop management with flash memory and a serial interface to support configurability, monitoring and management.

3.PTD08D210W - High performance dual 10 A output, non-isolated digital power drive (PowerTrain?) module

- Receive control signals from the digital controller and send parameters and status information back to the digital controller.
- The PowerTrain module and a digital power controller form an advanced, robust and easily configurable power management solution.
