New digital power controller provides a compact solutions for densely populated power systems

Intersil Corporation has expanded its family of power management ICs with a highly-integrated digital DC/DC power controller that, according to the company, helps to reduce design risk as well as time and cost for developers of complex power systems.

The ZL8800 is a Dual Channel/Dual Phase controller that uses a ChargeMode control loop technology to deliver a fast transient response without the need for compensation, reducing design time in the process. It provides best-in-class transient response for digital Point of Loads (POLs), saving on output capacitance and board space, important benefits for the advanced power systems found in the latest generation of base-stations, routers, and similar infrastructure designs.

These complex systems require designers to fully control and monitor every power rail in order to maximize reliability, and typically use monitors and sequencers to provide added functionality around the POL converters. The ZL8800 integrates all of these functions, so a designer can monitor and control every aspect of the power supply through a PMBus interface, without the need for additional parts. Telemetric data is available on the power supply, including temperature, input current, output current, input voltage, output voltage and fault status.

Each ZL8800 output can operate independently or together in a dual phase configuration for high current applications. The device supports a wide range of output voltages (0.54V to 5.5V) operating from input voltages from 4.5V up to 14V.

The company has also announced the latest generation of its PowerNavigator graphical user interface, enabling designers to leverage all the capabilities of the ZL8800 digital controller without writing a line of code. Designers can use the drag-and-drop utility to set up and control any power supply architecture, further simplifying the development effort.

“The ZL8800 is Intersil’s fourth generation digital controller. We have a proven track record of innovation in the digital power market, and our latest platform sets a new standard for capability and ease of use,” said Mark Downing, senior vice president of Intersil’s Industrial and Infrastructure Products. “Customers are now demanding the many benefits of digital power, and we’re delivering solutions that lets them realize those benefits simply and easily.”
