产品概述 返回TOP
The CXSU63223 Series is a Synchronous step-up DC/DC Converter with PFM Control. With the CXSU63223 Series, a step-up switching DC/DC converter can be configured by using an external coil 、 capacitor. The built-in MOSFET is turned off by a protection circuit when the voltage at the LX pin exceeds the limit to prevent it from being damaged
