Murata Power Block

Smart Point-of-Load Solution Digital Power Solution from ZMDI and Murata Power Solutions

Brief Description

Benefits

Murata Power Solutions’ surface-mount power blocks, combined with ZMDI’s ZSPM1000 true-digital single-phase PWM controller for non-isolated DC/DC supplies, enable fast and flexible power design of smart digital POL solutions.



Reference solutions are available with 25A and 35A current rating. For each solution a complete manufacturing kit is available including layout recommendation, optimized compensation for each power requirement, performance characteristics, and others.



Due to the digital technology, the smart POL solution is easy-to-use and optimized for high-performance applications requiring reliability and best-in-class transient performance.

A variety of additional current ratings up to 45A are planned. Some power blocks of Murata Power Solutions are still in development and will become available later this year.

Typical Applications 

Servers and Storage



Single-Rail/Single-Phase Supplies for Processors, ASICs, FPGAs, DSPs

Step-Response Performance The ability to dynamically change the control system response of the digital PWM controller ZSPM1000 leads to a performance not achievable from the competing class of analog controller.

ZSPM1000

This improved transient response will directly lead to, for a comparable transient voltage change, a reduction in the required output capacitance in the range of 40% to 50% leading to cost and size reductions in end user product.
