Renesas ZSPM1363 | Demoboard EVB02

Description

The ZSPM1363 is a configurable true-digital dual-phase PWM controller for high-current, non-isolated DC/DC supplies. It operates as a synchronous step-down converter in a single-rail and dual-phase con-figuration.The ZSPM1363 integrates a digital control loop, opti-mized 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 IDT Pink Power Designer™ graphical user interface (GUI) provides a user-friendly and easy-to-use interface to the device for communi-cation 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.
