True-digital 25A POL solution from ZMDI and Murata

ZMDI and Murata Power Solutions announce a true-digital 25A point-of-load (POL) solution. ZMDI’s ZSPM1025 single-phase digital PWM controller family ICs for non-isolated DC/DC supplies, combined with Murata Power Solution’s single-phase 25A surface-mount power block, provide a quick route to proven, high-performance smart digital power solutions.

ZMDI’s easy-to-use software enables the user to fully customise these solutions for optional digital communications via PMBus, output voltage range and output load. The digital control loop and compensators are preconfigured in the ZSPM1025 family devices. A downloadable complete construction kit is available, including a graphical user interface, layout guidelines and step-by-step instructions. It is ready to be immediately implemented in the application design.

Three smart digital power solutions with output currents up to 25A are now available. ZMDI plans to extend this family of single–phase, true-digital POL controllers for Murata Power Solution’s single-phase surface-mount power blocks with higher output current capabilities later this year and in early 2014.

The ZSPM1025 solutions that are available now and customised for the OKLP-X/25W12-C Murata Power Block include:

  • The ZSPM1025A featuring a PMBus programmable output voltage of 0.35-3.6V; four predefined, user-selectable output capacitance ranges; and configurable protection, sequencing and monitoring.
  • The ZSPM1025C featuring a pin-strap selectable output voltage of 0.6-1.2V and four predefined pin-strap selectable output capacitance ranges.
  • The ZSPM1025D featuring a pin-strap selectable output voltage of 1.2-3.4V and four predefined pin-strap selectable output capacitance ranges.

Tycho Raab, Product Line Manager, ZMDI, comments: “In combination with the highly reliable Murata Power Block technology, we are offering ready and tested POL solutions, which can be easily ‘pasted’ into any design. With our product’s simplicity of use and the solution readiness, you do not need highly-specialised knowledge to design power compensators.”
