DC/DC module provides POL power management

The ZL9101M is an encapsulated, highly integrated digital DC/DC power module that follows Intersil's Power Made Simple philosophy by providing customers with a building block that can be adapted to varying system power requirements.

The module, a quick and easy alternative for power solutions up to 12A, reduces the number of discrete components and complicated external ICs required to implement a complete POL power management solution.

The ZL9101M also delivers a thermally efficient package, significantly improving system reliability, according to the company.

For an out-of-the-box solution, system designers can take advantage of the ZL9101M's default configuration.

For additional design flexibility, the ZL9101M simplifies smart power management designs via the module's PMBus interface.

The PMBus, which is enabled by an internal Zilker Labs digital controller, provides maximum design flexibility and enables the real-time monitoring of voltage, current, temperature and other parameters.

The ZL9101M also includes adaptive performance optimisation algorithms to improve power-conversion performance and efficiency across the entire load range.

It reduces the bill of materials by integrating Mosfets, a power inductor and discrete components and the Intersil Zilker Labs digital DC/DC controller.

For applications requiring an output current greater than 12A, multiple ZL9101Ms can be paralleled using Digital-DC current-sharing technology.

Designers can configure a complete digital power solution with the Powernavigator graphical user interface (GUI).

The Powernavigator interface modifies module parameters with a click of the mouse - no soldering iron is required.

The ZL9101M is packaged in a 15 x 15mm thermally enhanced QFN with large thermal pads on the underside and exposed leads around the perimeter for visual solder joint inspection.

Very low thermal resistivity of 11.5C/W on the top of the package and 2.2C/W on the underside enables a power density of 61W/cm3.

The ZL9101M is available now and pricing starts at USD18.24 (GBP11.34) each in 1,000-piece quantities.
