This concept sits between a discrete point-of-load (PoL) design and that of a complete non-isolated PoL converter module. The power block is a non-isolated buck converter without the PWM controller.
The power block one-component design provides power handling components, tested and characterized for thermal and dynamic performance.
Most analog or digital PWM controllers can be used with the power block; however, the maximum benefits are achieved when coupled with ZMDI’s ZSPM1025 single phase digital PWM IC controller family.
The first power block product is the OKLP-X/25-W12-C, is a 25-amp module optimized for the ZMDI series of digital controllers that incorporate PMBus communications.
By combining the ZSPM1025 controller IC and the 25-amp Murata power block, engineers can implement a pre-configured 25-amp point-of-load solution. This includes a downloadable construction kit with step-by-step instruction and a software wizard, and is an FPGA designer-friendly solution. This implementation supports to four different output capacitor ranges without any additional design work.
The OKLP power block measures 12.7-by-17.02-by-10.7-millimeter and has a typical efficiency rating of 93.5 percent. Input voltage is around a nominal 12 volts DC and can accommodate the range of 7 to 13.2 volts DC.
