Overview
Description
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 configuration. The ZSPM1005 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 functions is provided. To facilitate user configuration of the part, a set of configuration options can be pre-programmed in the ZSPM1005 that can be selected by setting the values of two external resistors. 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, resistor options can be used to select the required configuration without a digital bus.
Features

ZSPM8001 Evaluation Kit for the ZSPM1005 PWM Controller and ZSPM9060 DrMOS
The ZSPM8001-KIT supports evaluation of DC/DC point-of-load (POL) applications. The kit incorporates the ZSPM1005 digital PWM controller IC and the ZSPM9060 DrMOS power output stage to form a "smart" buck converter (a.k.a. step-down DC-to-DC converter). The ZSPM8001-KIT Evaluation Kit hardware...
