The ZSPM1025C and ZSPM1025D are true-digital single-phase PWM controllers optimally configured for use with the Murata Power Solutions 25A Power Block OKLP-X/25 in smart digital power solutions. The ZSPM1025C and ZSPM1025D integrate a digital control loop, optimized for maximum flexibility and stability as well as load step and steady-state performance. In addition, a rich set of protection functions is provided. To simplify the system design, a set of optimized configuration options have been pre-programmed in the devices. These configurations can be selected by setting the values of two external resistors. Reference solutions are available complete with layout recommendations, example circuit board layouts, complete bill of materials and more.
Fast time-to-market using off-the-shelf, optimally configured controller and power block Fast configuration and design flexibility Simplified design and integration FPGA designer-friendly solution Highest power density with smallest footprint Pin-to-pin compatible with the ZSPM1025A PWM controller enabling point-of-load platform designs with or without digital communication Higher energy efficiency across all output loading conditions
