The MB39C031 contains 2ch buck DC/DC converter and 1ch LDO. It is possible to supply the main power supply line in a system by using only one chip. The current mode system is adopted for the DC/DC converter, and it is possible to use the chip inductor with the high switching frequency operation which contains internal SW FET. The MB39C031 contains the output setting resistor and the the phase compensation circuit, and contributes to reduce the number of external components and the mounting area. Also, it contains the CTL input pin which can control the ON/OFF for each CH, the Power Good signal output pin and the I2C communication interface, therefore it is easy to design the power supply sequence.
