IDT's ZSPM1025D single-phase digital PWM controller is optimally configured for use with the Murata Power Solutions 25A Power Block OKLP-X/25 and provides a quick route to proven, high-performance smart digital power solutions. The ZSPM1025D PWM controller integrates a digital control loop optimized for ultra-fast transient response, steady-state performance, stability and design flexibility. For improved system reliability, a rich set of protection and monitoring functions is provided. The ZSPM1025D features user-selectable, preconfigured compensators in the digital control loop optimized for use with the Murata Power Solutions 25A power block. IDT's easy-to-use Pink Power Designer™ software supports development of solutions with fully customizable output voltage and output capacitance. The software provides monitoring functions for controller operation, status and system errors. A downloadable reference solution is available, including a graphical user interface, layout guidelines, bill of materials and step-by-step instructions. It is ready to be immediately implemented in the application design.
