S6AP413A contains 3ch buck DC／DC converter and 1ch buck－boost DC／DC converter. S6AP413A cansupply the main power line in several systems by using only its chip. The current mode control is adopted forthe DC/DC converter, and it is possible to use the small chip inductor with the high switching frequencyoperation which contains internal switching FETs. S6AP413A contains the output setting resistor and thephase compensation circuit, and contributes to reduce the number of external components and its mountarea. Also it contains the CTL input pin which can control the ON/OFF for each DC/DC converter, the PowerGood signal output pin and I2C communication interface, therefore it is easy to design the power supplysequence. It is possible to tune in the output voltage exactly using the I2C communication.
