19-1678; Rev 0; 4/00 Network Interface Card Smart Regulator General Description The MAX1810 powers peripheral component interconnect (PCI) Ethernet network interface cards (NICs), modem cards, and other devices that utilize both the main and auxiliary (standby) voltages supplied by PCIcompliant systems. The device generates an uninterrupted +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. An auxiliary switch resistance of only 0.18Ω minimizes output droop from the +3.3V auxiliary supply.
