ROHM Introduces New Step-down Switching Regulators with Built-in Power MOSFET








Willich-Münchheide/Germany, April 18th 2013 – ROHM Semiconductor has announced new step-down switching regulators with a built-in 800mΩ Power MOSFET. The BD9G101G series provides 0.5A DC output with excellent line and load regulation for smart power management in a small SOT23 (SSOP6) package. The operating frequency is fixed at 1.5MHz, allowing the use of a small inductor and a ceramic capacitor in order to reduce space requirements. All phase compensation components are integrated as well.

The input voltage can vary from 6 to 42V, the internal reference voltage is set to 0.75V with an accuracy of typical ±1.5%. Ideally suited to facilitate step-down switching designs, the new device offers first-rate thermal resistance and multiple protection features such as internal over current protection, under voltage locked out and thermal shutdown . The operating temperature spans from -40°C to +105°C while the maximum junction temperature lays at 150°. Areas of deployment are industrial distributed power and automotive applications, battery powered equipment and medical OA instruments.

Key Features

  • High and Wide Input Range (VCC = 6V~42V)
  • 45V/800mΩ Internal Power MOSFET
  • 1.5MHz Fixed Operating Frequency
  • Feedback Pin Voltage 0.75V±1.5%
  • Internal compensated
  • Internal Over Current protection, Under Voltage Locked Out, Thermal shutdown
  • 0μA Shutdown Supply Current
  • 6-Lead SOT-23 package(SSOP6)
