TC7738WBG
TOSHIBA CMOS Integrated Circuit Silicon Monolithic
TC7738WBG
System Power IC
1. Overview
TC7738WBG is a system power IC which builds in 6 channels of a buck
DC-DC convertor and 2 channels of LDO. The IC operation voltage(3.3 V
or 5 V) can be changed using I2C interface and pin settings, power
supply can be provided to various systems. In addition, this product
incorporates the PROTECTION-SW for the input protection.
(*Refer to as hereinafter, Channel: CH, DC-DC convertor: DC-DC)
Package
2. Application
SSD (Solid State Drive), portable devices, etc.
