DC/DC Switching RegulatorsFunction
Ricoh’s DC/DC converters are equipped with internal or external output transistors.
The device equipped with an internal output transistor and the Lx pin is classified as DC/DC converter.
The device equipped with an external output transistor and the EXT pin is classified as DC/DC controller.
The device equipped with both internal and external output transistors is listed along with the DCDC converters.
A power MOSFET should be used with the external output transistor type.
To achieve high efficiency under heavy load, a MOSFET with a low ON resistance should be used.
To achieve high efficiency under light load, a MOSFET with a small gate capacity should be used.
As for MOSFETs, the maximum drain current should be higher than the maximum inductor current.
