Summit Microelectronics SMM665B
The SMM665B is an Active DC Output power supply Controller (ADOCTM) that monitors, margins and cascade sequences. The ADOC feature is unique and maintains extremely accurate settings of system supply voltages to within ±0.2% under full load. The device actively controls up to six DC/DC converters that use a Trim or Regulator VADJ/FB pin to adjust the output voltage.| Part No. | SMM665B |
