The XCL225/26 is a synchronous step-down Micro DC/DC converter with integrated coil in an ultra-small 3.0 x 3.0 x 1.6mm 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. With a P-Ch High Side Switch to ensure low Voltage operation and 100% max duty ratio, the XCL225/26 can operate from 3.0V~18.0V and deliver loads up to 500mA.
It’s designed for very high efficiencies at low output loads, with low quiescent current and automatic PFM/PWM mode or PWM only mode. The XCL225/26 includes a built in Current Limit Fold-back circuit, adjustable soft start and a power good output.

Torex has incorporated Copper CoolPosts into the DFN3030-10B package to connect the Inductor directly to the PCB footprint through the package.
This significantly increases the thermal performance of the package and give much better heat dissipation.
