Network Interface Card Smart Regulator

General Description

Features

The MAX1810 powers peripheral component intercon-

nect (PCI) Ethernet network interface cards (NICs),

modem cards, and other devices that utilize both the

main and auxiliary (standby) voltages supplied by PCI-

compliant systems. The device generates an uninter-

rupted +3.3V at up to 500mA from either a +5V main or

a +5V standby supply. When both +5V inputs fall below

+4.1V, an internal switch connects the +3.3V auxiliary

input to the output.

ꢀ Uninterrupted +3.3V Output

ꢀ Up to 500mA Output Current

ꢀ High-Power 0.9W SO-8 Package

ꢀ Thermal and Overcurrent Protection

ꢀ Only 1µF Output Capacitor

ꢀ Internal 0.18Ω +3.3V Auxiliary Switch

An auxiliary switch resistance of only 0.18Ω minimizes

output droop from the +3.3V auxiliary supply. In addi-

tion, the MAX1810 guarantees that no reverse current

flows from the output to any unbiased or inactive input,

and remains stable with as little as 1µF of output

bypass capacitance at its output.

ꢀ No Reverse Current to Inactive Inputs

The MAX1810 is available in a compact 8-pin high-

power (0.9W) SO package.
