DIOO Microcircuits DIO6011 Output Synchronous Step-Down Converter

DIOO Microcircuits DIO6011 Output Synchronous Step-Down Converter features high-efficiency and delivers up to 1A output currents. The DIOO Microcircuits DIO6011 operates over a wide 2.5V to 5.5V input voltage range. The converter integrates a main switch and a synchronous switch with low RDS(ON) to minimize conduction loss. A low output voltage ripple and small external inductor and capacitor sizes are achieved with greater than 1.5MHz switching frequency.

Features

  • Low RDS(ON) for internal switches (top/bottom)
  • 230mΩ/170mΩ, 1.0A
  • 2.5-5.5V input voltage range
  • 40μA typical quiescent current
  • Highlight load efficiency
  • A high switching frequency 1.5MHz minimizes the external components
  • Internal soft-start limits the inrush current
  • 100% dropout operation
  • Green package SOT23-5 is pin-compatible

Applications

  • Portable navigation device
  • Set-top box
  • USB dongle
  • Media player
  • Smartphone
