Fairchild Semiconductor International's New Single-Chip BCDMOS Power Switch Boasts High Efficiency, Lowers Switch Mode Power Supply Component Count.

Business Editors & High-Tech Writers

SAN JOSE, Calif.--(BUSINESS WIRE)--March 22, 2001

Fairchild Semiconductor International (NYSE:FCS) introduces the FSDH0165 power switch -- a voltage mode PWM controller and SenseFET (LDMOS) power switching element integrated into a single chip and packaged in an 8-lead DIPH.

Designed for adapter/chargers for mobile phones and PDAs and other low-power switch mode power supply (SMPS) applications, the FSDH0165 consumes just 0.3W, compared to 0.5W for typical alternatives. Power consumption and space efficiencies are achieved through the use of a 650 V BCDMOS process resulting in fewer external components and impressive reduction in PC board space requirements.

The FSDH0165 is a self-biased and protected linear control current-to-duty cycle converter with an open drain output. The device operates from 6.7V to 21V at a frequency of 100KHz. It is equipped with built-in start-up switch eliminating the need for an external start up resistor. Other features include auto-restart to minimize power consumption in standby mode, overload protection, over current protection and internal thermal shutdown protection. The DIPH package enhances thermal conductivity by connecting a single, wide lead to two ground pins.

When used in combination with the Fairchild FAN7563 controller IC, the FSDH0165 provides a space saving, two-IC solution for low-power battery charging applications. An application note is available.
