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.

The PWM controlled XCL303 series can be selected for applications where low noise is important, and the PWM/PFM automatic

switching controlled XCL304 series can be selected for applications where high efficiency at light load current and low noise at

high load current is important.

The XCL303/XCL304 series allows users to select either a PWM control or PWM/PFM automatic switching control method,

which are optimum for applications where low noise and high efficiency are important.

Output voltage can be adjusted within the range of -1.2V to -6.0V using externally mounted resistors.
