Key Features

  • battery-powered instruments. Consists of an oscillator, a PFM control circuit, a driver Pin EXT to external MOSFET, a reference voltage unit, an error amplifier. A low ripple and high efficiency step-up DC/DC converter can be constructed of this RCR2562 IC with only six external components. The RCR2562 works on ultra low start-up voltage, typically max start-up voltage less than 1.1V at 1mA load current.
  • Low Start-up Voltage, 1.1V at 1mA.
  • Minimal Number of External Components (.
