XCL301 Overview
The XCL301 series is a inverting micro DC/DC converter which integrates a P-channel FET, an inductor and a control IC in one tiny package (2.5mm×2.0mm, h=1.00mm max). A wide operating voltage range of 2.7V to 5.5V enables support for applications that require an internally -3.3V fixed output voltage. The XCL301 series uses automatic PFM/fixed off time PWM.
