  • 概述

    The R5540 Series are CMOS-based load switch IC. The R5540 is an ideal switch to supply the power from the secondary power source such as the output of a step-down DC/DC converter to the load circuit. Due to a built-in N-channel transistor with low on-resistance of 120mΩ, R5540 provides a low dropout voltage. In addition to a peak current limit circuit, R5540 has a short current limit circuit and a soft start function. Due to a reverse current protection circuit, R5540 prevent a reverse current at off state.

    Besides the low supply current by CMOS, the R5540 has low voltage with an input voltage from 0.75V (002) and 0.8V (004). Accordingly, the device supports highly integrated, low voltage-driven LSI as a rear stage of the DC/DC converter. Standby mode and auto-discharge function are also available. A 1mm square DFN(PLP)1010-4F package called a flip chip is available.
