ZSPM1063

True Digital PWM Controller (Single-Phase, Single-Rail)

The ZSPM1063 is a configurable true-digital single-phase 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 ZSPM1063 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. The PC-based ZMDI 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, including protection and sequencing.
