CUI INC – 90A Digital PoL Module NDM3Z-90, Provides Wide Range of Control and Monitoring Features

pg6_CUIINC_image1CUI-logo       NPI_LOGO
The new NDM3Z-90 non-isolated module, available in low-profile vertical and horizontal packages, provides an output of up to 90A. It is intended to meet the requirements of the latest FPGAs, processors and microcontrollers for very high power together with sophisticated control and monitoring capabilities.

The module incorporates a range of advanced digital features, including programmable output range, active current sharing, voltage sequencing, voltage tracking, synchronization and phase spreading. It also implements programmable soft-start and soft-stop functions.

The NDM3Z-90 is based on Intersil’s ZL8801 digital power controller. Thanks to the ZL8801’s ChargeModeTM Control technology, no compensation is required, allowing the modules to autonomously balance the trade-offs between dynamic performance and system stability on a continuous basis. With this feature, designers are able to bypass the traditional practice of building in margins to account for factors such as component aging, manufacturing variations and temperature, which lead to higher component cost and longer design cycles.

The module offers class-leading efficiency and transient response. Efficiency is 91.4% when supplying 1V DC from a 12V DC input, at 50% load. Up to four modules may be connected in parallel in an active current-sharing scheme to produce an output of up to 360A.

All digital features are dynamically programmable via PMBus commands or through CUI’s easy-to-use Novum ACETM GUI.
