XCM524 Series
600mA Synchronous Step-Down DC/DC Converter + 500mA LDO with Delay Function Voltage Detector
ETR2428-003
˙GENERAL DESCRIPTION
The XCM524 series is a multi combination module IC which comprises of a 600mA driver transistor built-in synchronous step–down DC/DC converter and a high speed, high current LDO regulator with voltage detector function. The device is housed in small USP-12B01 package which is ideally suited for space conscious applications. The DC/DC converter and the LDO blocks are isolated in the package so that noise interference from the DC/DC to the LDO regulator is minimal. The DC/DC converter block with a built-in 0.42ЊP-channel MOS driver transistor and 0.52ЊN-channel MOS switching transistor, designed to allow the use of ceramic capacitors.
