True Digital PWM Controller

(Single-Phase, Single-Rail)

ZSPM1035C /

ZSPM1035D

Datasheet

Brief Description

The ZSPM1035C and ZSPM1035D are true-digital

single-phase PWM controllers optimally configured

for use with the Murata Power Solutions 35A Power

Block OKLP-X/35-W12-C in smart digital power

solutions.

The ZSPM1035C and ZSPM1035D integrate a digi-

tal control loop, optimized for maximum flexibility and

stability as well as load step and steady-state perfor-

mance. 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.
