Description
☆Green Operation Compatible
The XCL223/XCL224 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.25mm×1.5mm, h=0.75mm).An internal coil simplifies the circuit and enables minimization of noise and
other operational trouble due to the circuit wiring.A wide operating voltage range of 2.5V to 5.5V enables support for applications
that require an internally fixed output voltage (0.8V to 3.6V).The XCL223/XCL224 series us
