2-Channel Synchronous Step-down DC/DC Converter IC

MB39A138

 MB39A318

By adopting the bottom detection comparator method, this product is capable of stable operation and rapid response even with large difference between input and output voltages and rapid load changes. It does not require phase compensation to prevent oscillation. System construction with a small number of parts is enabled through the use of a built-in bootstrap diode, which is required for FET operation.
This product has an output capacity of low voltage of approximately 1.0V with current at 10A or larger. It is capable of providing simultaneous power management to two destinations such as a LSI of core and I/O or a memory.
Its soft-start discharge function also enables simple power management sequence control when multiple voltages are used.

 Application example

MB39A130A is 1-channel DC/DC converter IC adapting the bottom detection comparator method. Please see the corresponding specifications as well as 2-channel DC/DC converter IC, MB39A138.
