ZSPM1000 True Digital PWM Controller (Single-Phase, Single-Rail) Brief Description Benefits The ZSPM1000 is a configurable true-digital singlephase PWM controller for high-current, non-isolated DC/DC supplies. It operates as a synchronous stepdown converter in a single-rail and single-phase configuration. The ZSPM1000 integrates 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 and monitoring functions is provided. On-chip, non-volatile memory (NVM) and 2 * an I C™ interface facilitate configuration. The PC-based ZMDI’s Pink Power Designer™ provides a user-friendly and easy-to-use interface to the device for communication and configuration. It can guide the user through the design of the digital compensator and offers intuitive configuration methods for additional features, such as protection and sequencing. Available Support Programmable 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 Restart and delay Support for SMOD and ZCD drivers Fuse-based NVM for improved reliability Operation from a single 5V or 3.3V supply Optional PMBus™ address selection without external resistors I2C™ is a registered trademark of NXP. ** Subject to product type.
