ZSPM1035A Datasheet, PDF (1/45 Pages) List of Unclassifed Manufacturers – True Digital PWM Controller (Single-Phase, Single-Rail)

True Digital PWM Controller
(Single-Phase, Single-Rail)
ZSPM1035A
Datasheet
Brief Description
The ZSPM1035A is a flexible true-digital single-
phase PWM controller optimally configured for use
with the Murata Power Solutions 35A Power Block
OKLP-X/35-W12-C in smart digital power solutions.
The ZSPM1035A 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 func-
tions 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 ZSPM1035A for com-
munication, monitoring, and configuration of the pro-
tection 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.
