ZSPM1025C

True Digital PWM Controller (Single-Phase, Single-Rail) ZSPM1025C / ZSPM1025D Datasheet Brief Description 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. Features Application-optimized digital control loop Advanced, digital control techniques Tru-sample Technology™ State-Law Control™ (SLC) Sub-cycle Response™ (SCR) Improved transient response and noise immunity Protection features Over-current protection Over-voltage protection (VIN, VOUT) Under-voltage protection (VIN, VOUT) Overloaded startup Continuous retry (“hiccup”) mode for fault conditions Pre-programmed for optimized use with Murata Power Solutions 25A Power Block OKLP-X/25 2-pin configuration for loop compensation, output voltage, and slew rate. Operation from a single 5V or 3.3V supply Be...
