True Digital PWM Controller
(Single-Phase, Single-Rail)
ZSPM1063
Datasheet
Brief Description
The ZSPM1063 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 ZSPM1063 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 communica-
tion 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.
