Torex XCL247/48
XCL247/48 – 36 V 0.6 A Step-Down DC/DC with Integrated Inductor
The XCL247/48 is a synchronous step-down Micro DC/DC converter with integrated coil in an ultra-small 3.0 x 3.0 x 1.7 mm DFN3030-10B package. A stable and efficient power supply circuit can be configured by simply adding only two ceramic capacitors externally thereby contributing to PCB space saving and the shortening of development time.
Integration of the coil simplifies the board layout and minimises any unwanted radiated noise. The XCL247/48 operates from 3.0 ~36.0 V and deliver loads up to 600 mA. The output voltage can be set in the range of 2.8 to 6.0 V using external resistors.
Designed for very high efficiencies at low output loads, with low quiescent current and automatic PWM/PFM mode or F-PWM only mode, the XCL247/48 includes a built in Current Limit Fold-back circuit, adjustable soft start and a power good output.
