Description
☆Green Operation Compatible
The XCL219/XCL220 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control
IC in one tiny package (2.0mm×2.5mm, h=1.0mm).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 XCL219/XCL220 series use
