ZSPM1363
ZSPM1363 True Digital PWM
Datasheet
Controller (Dual-Phase, Single-Rail)
Brief Description
Features
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.

Programmable digital control loop
Dual-phase, single-rail solution
Power modes (phase addition/drop)
Optional PMBus™ address selection without
external resistors
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.

Improved transient response and noise immunity
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.
