Intersil's Narrow VDC Battery Charger Controller Improves Efficiency and Extends Battery Life in Notebook Computers

Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today introduced the ISL6257, a narrow VDC (voltage direct current) charger controller for Li-Ion/Li-Ion polymer batteries in notebook computers. This device is designed to meet the NVDC-I requirements for better efficiency and longer battery life.

— Intersil's ISL6257 Provides ±0.5% Charge Voltage Accuracy and a Programmable Charge Current Limit, Adapter Current Limit and Charge Voltage for Configuration to a Wide Range of Li-Ion/Li-Ion Polymer Battery Packs

The ISL6257, the only true narrow VDC charger controller on the market, offers the best overall accuracy and features narrow VDC output, which allows the system to operate from the regulated charger instead of the adapter. The use of the Vbat as the system voltage as opposed to the adapter allows the notebook to run at a maximum of 12.6V instead of adapter voltage, increasing the overall efficiency of the system and improving battery life and thermal management in the system.

The ISL6257 is the only NVDC-I charger on the market that is optimized for this application, allowing customers to run their laptops at much lower battery voltages.
