General Description
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.
An auxiliary switch resistance of only 0.18
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.
The MAX1810 is available in a compact 8-pin high-
power (0.9W) SO package.
