True Digital PWM Controller
(Single-Phase, Single-Rail)
ZSPM1025C /
ZSPM1025D
Datasheet
Brief Description
The ZSPM1025C and ZSPM1025D are true-digital
single-phase PWM controllers optimally configured
for use with the Murata Power Solutions 25A Power
Block OKLP-X/25 in smart digital power solutions.
The ZSPM1025C and ZSPM1025D integrate 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
functions is provided.
To simplify the system design, a set of optimized
configuration options have been pre-programmed in
the devices. These configurations can be selected
by setting the values of two external resistors.
Reference solutions are available complete with
layout recommendations, example circuit board
layouts, complete bill of materials and more.
