XCM519 Series
600mA Synchronous Step-Down DC/DC Converter + Low Voltage Input LDO
■GENERAL DESCRIPTION
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. A low output voltage and low On-resistance LDO regulator is added in series to the DC/DC output so that one another low output voltage is created with a high efficiency and low noise. With comparison to the dual DC/DC solution, one inductor can be eliminated which results in parts reduction and board space saving.

* XCM519 series A type is a fixed PWM because that the “CE/MODE Control Logic” outputs a low level signal to the “PWM/PFM Selector”.
* XCM519 series B type is an auto PWM/PFM switching because the “CE/MODE Control Logic” outputs a high level signal to the “PWM/PFM Selector”.
*Diodes inside the circuit are an ESD protection diode and a parasitic diode.
