XCL239/XCL240 Step-Down Micro DC/DC Converters

Torex Semiconductor XCL239/XCL240 Step-Down Micro DC/DC Converters are 1.0A synchronous devices with an integrated inductor and control IC in a tiny 2.5mm x 2.0mm x 1.04mm (LxWxH) package. An internal coil simplifies the circuit and minimises noise and other operational troubles due to the circuit wiring. The output voltage is internally set from 0.8V to 3.6V in 0.05V increments.
