ZSPM1000 Datasheet, PDF (1/3 Pages) List of Unclassifed Manufacturers – True Digital PWM Controller (Single-Phase, Single-Rail)

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
an I²C™ ^* 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.
