Intersil’s New ZL8101 Delivers Industry’s Most Flexible Digital Power Management Solution

The ZL8101 is an adaptive digital DC/DC PWM controller with auto compensation that provides a single phase solution with output currents up to 50A. Designed to work with an external driver and with DrMOS solutions, it can be used in parallel for current sharing between multiple ZL8101 devices. It also can be deployed as a flexible building block for 12V and 5V down conversion where size, efficiency and monitoring are critical. The ZL8101 uses a dedicated, optimized, state machine for generating precise PWM pulses and a proprietary MCU for set-up and optimization.

By automatically compensating the power supply, designers using the ZL8101 can save weeks of design time and significantly improve reliability in a wide range of applications by relieving designers of the need for special tools, knowledge or experience to optimize performance. It extends Intersil’s global leadership in digital power management technology, and is ideal for wired and wireless systems, data communications, and power supply applications.
