ZSPM1363 True Digital PWM
Controller (Dual-Phase, Single-Rail)
ZSPM1363
Datasheet
Brief Description
The ZSPM1363 is a configurable true-digital dual-
phase PWM controller for high-current, non-isolated
DC/DC supplies. It operates as a synchronous step-
down converter in a single-rail and dual-phase con-
figuration.
The ZSPM1363 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 communi-
cation 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.
