ZSPM1035C / True Digital PWM Controller ZSPM1035D (Single-Phase, Single-Rail) Datasheet Brief Description Benefits The ZSPM1035C and ZSPM1035D are true-digital Fast time-to-market using off-the-shelf, optimally single-phase PWM controllers optimally configured configured controller and power block for use with the Murata Power Solutions 35A Power Fast configuration and design flexibility Block OKLP-X/35-W12-C in smart digital power Simplified design and integration solutions. FPGA designer-friendly solution The ZSPM1035C and ZSPM1035D integrate a digi- Highest power density with smallest footprint tal control loop, optimized for maximum flexibility and Pin-to-pin compatible with the ZSPM1035A PWM stability as well as load step and steady-state perfor- controller enabling point-of-load platform designs mance. In addition, a rich set of protection functions with or without digital communication is provided. Higher energy efficiency across all output loading To simplify the system design, a set of optimized conditions configuration options have been pre-programmed in the devices. These configurations can be selected by setting the values of two external resistors. Available Support Reference solutions are available complete with Evaluation Kit layout recommendations, example circuit board Reference Solutions layouts, complete bill of materials and more.
