ZSPM10x5
True Digital PWM Controller Family
Brief Description
The ZSPM10x5 single-phase digital PWM controller
family is optimally configured for use with the Murata
Power Solutions 25A and 35A Power Blocks in
smart digital power solutions.
The ZSPM10x5 controllers integrate a digital control
loop, optimized for load-step transient response,
steady-state performance, stability, and maximum
flexibility. For improved system reliability, a rich set
of protection and monitoring functions is provided.
The ZSPM10x5 family features a user-selectable,
preconfigured digital control loop and compensators
optimized for use with the Murata Power Solutions
25A power block OKLP-X/25-W12-C and 35A power
block OKLP-X/35-W12-C.
Downloadable reference solutions are available,
including ZMDI’s Pink Power Designer™ GUI, layout
guidelines, bill of materials, and step-by-step instructions.


ZSPM10x5A features PMBus™ programmable
output voltage (0.35V-3.60V); four predefined
output capacitance ranges; and configurable
protection, sequencing, and monitoring.
ZSPM10x5C features pin-strap selectable output
voltage (0.62V-1.20V) and four predefined output
capacitance ranges.
ZSPM10x5D features pin-strap selectable output
voltage (1.25V-3.40V) and four predefined output
capacitance ranges.
