DC/DC Converter Application Note

The Diode Rectifier and The Synchronous Rectifier

Ricoh step-down DC/DC converters can be classified into diode rectifier type and synchronous rectifier type. The diode rectifier type is uses a schottky diode, and the synchronous rectifier type uses a low side MOS transistor. In most cases, Ricoh's synchronous rectifier type DC/DC converters have built-in high side and low side MOS transistors except for the R1242S.
