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 PCI-compliant systems. The device generates an uninterrupted+3.3V at up to 500mA from either a +5V main ora +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 drop from the +3.3V auxiliary supply. In addition,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.
