FAN5240QSCX Description

Short technical summary and product information.

The FAN5240QSCX is a multi-phase PWM controller designed for CPU core power applications, specifically for AMD Mobile Athlon™ and Duron™ processors. It provides a configurable output voltage range from 0.93V to 2V, with a ±1% reference precision over temperature. The controller supports an input voltage range of 6V to 24V and features 2-phase interleaved switching for improved efficiency and dynamic response.

 

Key features include high efficiency, exceeding 90% over a wide load range and 80% at light loads. It incorporates Voltage Feed-Forward and Average Current Mode control for excellent dynamic response. The device also includes fault protections such as over-voltage, over-current, and thermal shutdown. The FAN5240QSCX is available in a 28-QSOP package and operates within a temperature range of -10°C to 85°C.

 

This switching controller is suitable for applications requiring precise voltage regulation for CPU cores and graphic chips. Its design facilitates compliance with AMD's Power Now™ technology, allowing for controlled voltage transitions during operation. The surface mount package is standard for modern electronic assemblies.
