Description

The RC5060 is an ACPI Switch Controller for the Camino, Whitney, and Tehama Platforms. It provides various voltages such as 3.3V Dual for PCI, 3.3V for SDRAM, 2.5V Dual for RAMBUS, and 5V Dual. With an onboard precision low TC reference, it ensures tight tolerance voltage regulation without the need for expensive external components. The RC5060 also offers integrated Power Good and Current Limiting to protect each output, as well as power-up softstarts for the linear regulators. It comes in a 20 pin SOIC package.
