ZSPM2000
True Digital PWM Controller with Integrated MOSFET Driver
Brief Description
Benefits
The ZSPM2000 is a configurable true-digital singlephase PWM controller for high-current, non-isolated
DC/DC supplies. The ZSPM2000 includes a highspeed 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
2
*
an I C™ interface facilitate configuration.

ZMDI’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.
