Description
The ZSPM2000 is a configurable true-digital single-phase PWM controller for high-current, non-isolated DC/DC supplies. The ZSPM2000 includes a high-speed MOSFET driver for a synchronous step-down converter in a single-rail and single-phase configuration. The ZSPM2000 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 an I²C interface facilitate configuration. IDT’s PC-based Pink Power Designer™ graphical user interface (GUI) 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.
