ZSPM1005 True Digital PWM Controller (Single-Phase, Single-Rail) Brief Description Benefits The ZSPM1005 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 ZSPM1005 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. To facilitate user configuration of the part, a set of configuration options can be pre-programmed in the ZSPM1005 that can be selected by setting the values of two external resistors. ZMDI’s Pink Power Designer™; a PC-based, userfriendly interface to the ZSPM1005, can be used to expedite the design of the digital compensator. It offers intuitive configuration methods for additional features, such as protection and sequencing. Once the part is programmed, the resistor options can be used to select the required configuration without a digital bus. Available Support Features 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 one-time programmable (OTP) nonvolatile memory for improved reliability Operation from a single 5V or 3.3V supply 2-pin configuration for compensation, output voltage, and more Fast configuration and design flexibility improves time-to-market Simplified design and integration FPGA designer-friendly solution Highest power density with smallest footprint Pin-to-pin compatible with the ZSPM1000 PWM controller enabling point-of-load power module platform designs with or without digital communication Higher energy efficiency across all output loading conditions Evaluation Kit PC-based Pink Power Designer™ Physical Characteristics Operation temperature: -40°C to +125°C VOUT max: 5V Lead free (RoHS compliant) 24-pin QFN package (4mm x 4mm) ZSPM1005 Typical Application Diagram For more information, contact ZMDI via [email protected]. © 2014 Zentrum Mikroelektronik Dresden AG — Rev.2.00 — October 14, 2014.
