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

Built-in Autocompensation Saves Design Time, Improves Reliability

MILPITAS, CA--(Marketwire - Mar 14, 2013) - Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high-performance analog, mixed signal and power management semiconductors, today introduced its newest digital power supply management solution, featuring automatic compensation and adaptive performance optimization algorithms that significantly improve power conversion efficiency.

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.

Features and Specifications

  • Designed to work with drivers like the ZL1505 or ISL6611A phase doubler
  • The PMBus interface allows real-time monitoring of current, voltage and temperature
  • PMBus interface guarantees full control over power supply operation and configuration
  • Most operating features can be configured by simple pin-strap/resistor selection or through the SMBus™ serial interface.

Pricing and Availability
The ZL8101 is available now in QFN-32 packages, with prices starting at $3.10 each in 1,000-unit quantities. For more information please visit:
