TC1313 Overview
The TC1313 device bines a 500 mA synchronous buck regulator and 300 mA Low-Dropout Regulator (LDO) to provide a highly integrated solution for devices that require multiple supply voltages. The unique bination of an integrated buck switching regulator and low-dropout linear regulator provides the lowest system cost for dual-output voltage applications that require one lower processor core voltage and one higher bias...
