XCL225/XCL226 Series 0.5A Inductor Built-in Step-down “micro DC/DC” Converter ETR28014-004 ■GENERAL DESCRIPTION The XCL225/XCL226 series are 18V operation synchronous step-down DC/DC converter ICs with a built-in high-side / low-side driver transistor. The XCL225/XCL226 series has operating voltage range of 3.0V～18.0V and it can support 500mA as an output current with high-efficiency. Compatible with Low ESR capacitors such as ceramic capacitors for the load capacitor (CL). 0.75V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.0V to 15.0V using external resistors (RFB1, RFB2). 1.2MHz can be selected for the switching frequency.
