F72603R

1.

General Description

The F72603R is a fully compliant ACPI controller IC. Used with an ATX power supply, this chip integrates

one linear controller, four switch controller, monitoring and power signal control function into 28 pin SSOP

package. The F72603R not only provides one adjustable linear regulator and four switch controllers but

also integrates a charge pump engine to provide higher driving voltage for appropriate gate during standby.

It also integrates Power OK and Reset signal circuit. On the other hand, this chip offers current limiting that

protect each output, and provides soft-start function for linear regulator to avoid rush current. The power

LED and suspend LED are programmable and compliant with PC2001. This chip is in VSB 5V operation

and 28pin SSOP package.
