ZSPM1035DA1W0 Overview

PQFN / 24 / 4X4MM# G1 - TAPE&REE;

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.
Benefits
Fast time-to-market using off-the-shelf, optimally
configured controller and power block
