GENERAL DESCRIPTION
A wide 1.8V to 5.5V input voltage range allows for operations from industry standard 1.8V, 3.3V and 5V power rails. Current limit thresholds can be programmed accurately and independently for each channel via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during turn on/off. Built-in over current, under voltage lockout (UVLO), reverse current and over temperature protections insure safe operations under abnormal operating conditions. XRP2527 and XRP2528 are offered respectively in RoHS compliant “green”/halogen free 3mm x 3mm 8-pin and 10-pin TDFN packages.APPLICATIONS
