ZSPM1000
True Digital PWM Controller (Single-Phase, Single-Rail)
Brief Description
Benefits
The ZSPM1000 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 ZSPM1000 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.
The PC-based ZMDI’s Pink Power Designer™ 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.
