XCM519 Series GENERAL DESCRIPTION www.DataSheet4U.com ETR2421-003 600mA Synchronous Step-Down DC/DC Converter + Low Voltage Input LDO The XCM519 series is a multi combination module IC which comprises of a 600mA driver transistor built-in synchronous step–down DC/DC converter and a low voltage input LDO regulator. The device is housed in small USP-12B01 package which is ideally suited for space conscious applications. Battery operated portable products require high efficiency so that a dual DC/DC converter is often used. The XCM519 can replace this dual DC/DC to eliminate one inductor and reduce output noise. The DC/DC converter and the LDO regulator blocks are isolated in the package so that noise interference from the DC/DC to the LDO regulator is minimal.
