SC4524EVB中文资料升特数据手册PDF规格书

描述 Description

The SC4524 is an adjustable frequency peak current mode step-down switching regulator with an integrated 2.3A, 30V switch. The SC4524 can be programmed up to 1.5MHz. This allows the use of small inductor and ceramic capacitors, resulting in very compact power supplies. The SC4524 is suitable for next generation XDSL modems, set-top boxes and point of load applications.
