XCL304 - Negative Output Voltage micro DC/DC Converter

Download the XCL304 datasheet PDF. This datasheet also covers the XCL303 variant, as both devices belong to the same negative output voltage micro dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The XCL303/XCL304 series are small coil-integrated negative voltage micro DC/DC converter IC.

The oscillating frequency is a fast 2.5MHz and the small 2.5 x 2.0 x 1.0mm package contributes significantly to space saving in PCB area.

XCL303/XCL304 Series ETR28016-001 Inductor Built-in Negative Output Voltage “micro DC/DC” Converters ☆Green Operation Compatible ■GENERAL DESCRIPTION The XCL303/XCL304 series are small coil-integrated negative voltage micro DC/DC converter IC. The oscillating frequency is a fast 2.5MHz and the small 2.5 x 2.0 x 1.0mm package contributes significantly to space saving in PCB area. Further, integrating the coil together with the DC/DC simplifies the circuit board layout and minimizes potential noise interference. Compared to a charge pump type solution, the switching method of the XCL303/XCL304 maintains a stable output voltage even when the input voltage fluctuates. In addition, this new micro DC/DC can support larger output current than a charge pump solution.
