ZSPM1000
True Digital PWM Controller (Single-Phase, Single-Rail)
Brief Description
The ZSPM1000 is a configurable true-digital single-
phase PWM controller for high-current, non-isolated
DC/DC supplies. It operates as a synchronous step-
down converter in a single-rail and single-phase con-
figuration.
The ZSPM1000 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

interface facilitate configuration.
The PC-based ZMDI’s Pink Power Designer™ pro-
vides 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 com-
pensator and offers intuitive configuration methods
for additional features, such as protection and
sequencing.
Benefits
Fast configurability and design flexibility
Simplified design and integration
Reduced component count through system level
integration
