True Digital PWM Controller
(Single-Phase, Single-Rail)
ZSPM1025A
Datasheet
Brief Description
The ZSPM1025A is a flexible true-digital single-
phase PWM controller optimally configured for use
with the Murata Power Solutions 25A Power Block
OKLP-X/25-W12-C in smart digital power solutions.
The ZSPM1025A integrates a digital control loop,
optimized 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.
IDTâs PC-based Pink Power Designer⢠graphic
user interface (GUI) provides a user-friendly and
easy-to-use interface to the ZSPM1025A for
communication, monitoring, and configuration of the
protection and sequencing features.
A downloadable reference solution is available,
including a graphical user interface, layout guide-
lines, bill of materials, and step-by-step instructions.
