Step-down micro DC/DC converters have integrated coil
https://www.electronics-lab.com/step-micro-dc-dc-converters-integrated-coil/
Step-down micro DC/DC converters make up the XCL225/XCL226 series from Torex Semiconductor. The 18V coil-integrated converters contribute to space-saving on the board and a shorter development time because a circuit can be configured by simply adding two external ceramic capacitors, explains Torex. An internal coil lowers EMI and also simplifies the board layout and makes […]
