1 General Description

The F72569 is a fully compliant ACPI controller IC specific for AMD K8 CPU platform. The chip is used with an ATX

power supply, and it integrates synchronous PWM controllers, regulators, several linear controllers, switching

signals, monitoring and control function into a 48 pin LQFP package. Its operation mode (sleep or active) is

selectable through some control signals. The F72569 provides 3 switch signals which can provide 5V

DUAL

, 5V

USB

3.3V

DUAL

etc. The F72569 can also provide 5 linear regulators for system requirements. This chip integrates a

charge pump engine to provide higher driving voltage for appropriate gate during standby. Besides, this chip offers

current limiting that protects each PWM outputs, and provides soft-start for a linear regulator to avoid rush current.

The power LED is programmable and compliant with PC2001. Moreover, this high-performance chip integrates I

interface and provides adjustable linear controllers mechanism for dynamic over/under-voltage use. This chip is in

a 48pin LQFP package and powered by 5VSB.
