ZSPM1005

True Digital PWM Controller

(Single-Phase, Single-Rail)

Datasheet

Brief Description

Benefits

The ZSPM1005 is a configurable true-digital single-

phase PWM controller for high-current, non-isolated

DC/DC supplies. It operates as a synchronous step-

down converter in a single-rail and single-phase con-

figuration.

•

Fast configuration and design flexibility improves

time-to-market

•

Simplified design and integration

FPGA designer-friendly solution

Highest power density with smallest footprint

The ZSPM1005 integrates a digital control loop, opti-

mized for maximum flexibility and stability as well as

load step and steady-state performance. In addition,

a rich set of protection and monitoring functions is

provided. To facilitate user configuration of the part,

a set of configuration options can be pre-prog-

rammed in the ZSPM1005 that can be selected by

setting the values of two external resistors.

Pin-to-pin compatible with the ZSPM1000 PWM

controller enabling point-of-load power module

platform designs with or without digital

communication

•

Higher energy efficiency across all output loading

conditions

Available Support

IDT’s Pink Power Designer™; a PC-based, user-

friendly interface to the ZSPM1005, can be used to

expedite the design of the digital compensator. It

offers intuitive configuration methods for additional

features, such as protection and sequencing. Once

the part is programmed, the resistor options can be

used to select the required configuration without a

digital bus.
