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.
Fast & easy-to-use solution for POL applications Easy and intuitive configuration with Graphical User Interface (GUI) to optimize performance FPGA designer friendly solution High power density and small footprint Reduction of output capacitors and component count High reliability Digital communication simplifies monitoring for system power and thermal management Higher energy efficiency on system level

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