Digital power controller delivers auto-compensation, high integration

The ZL8800 dual-channel/dual-phase controller built with the ChargeMode control loop technology enables transient response without the need for compensation. It provides best-in-class transient response for digital POLs, saving on output capacitors and board space.

The IC integrates functions, so that a designer can monitor and control every aspect of the power supply through a PMBus interface, without the need for additional parts. Available data for the power supply includes temperature, input current, output current, input voltage and output voltage. The device output can operate independently or together in a dual phase configuration for high current applications. It supports output voltages from 0.54 to 5.5 V, operating from input voltages from 4.5 up to 14 V. The latest generation of the PowerNavigator user interface enables engineers to leverage all of 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.
