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.
IDT’s 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.
Features
Programmable digital control loop
Advanced digital control techniques
Tru-sample Technology™
State-Law Control™ (SLC)
Sub-cycle Response™ (SCR)
Improved transient response and noise immunity
Protection features
Over-current protection
Over-voltage protection (VIN, VOUT)
Under-voltage protection (VIN, VOUT)
Overloaded startup
Continuous retry (“hiccup”) mode for fault
conditions
Fuse-based NVM for improved reliability
Operation from a single 5V or 3.3V supply
Optional PMBus™ address selection without
external resistors
Benefits
Fast time-to-market using off-the-shelf, optimally
configured controller and power block
Fast configurability and design flexibility
Simplified design flow and high reliability via
proven system design solution
Reduced component count through system level
integration
Simplified monitoring for system power and
thermal management
Pin-to-pin compatible with the ZSPM1025C and
ZSPM1025D PWM controllers, enabling point-of-
load platform designs with or without digital
communication
Higher energy efficiency across all output loading
conditions
