The SP6648 is an ultra-low quiescent current, high efficiency step-up DC/DC converter ideal for single cell, dual cell alkaline and Li-ion battery applications such as digital still cameras, PDAs, MP3 players and other portable devices. The SP6648 combines the high-load efficiency associated with PWM control, with the low quiescent current and excellent light-load efficiency of PFM control. The SP6648 features 12μA quiescent current, synchronous rectification, a 0.3Ω charging switch, anti-ringing inductor switch, programmable low-battery detect, undervoltage lockout and programmable inductor peak current. The device can be controlled by a 1nA active LOW shutdown pin.

  • Ultra-low 12µA quiescent current
  • 400mA output current at 2.6V input: 3.3VOUT
  • 94% efficiency from 2 cell to 3.3VOUT
  • Wide input voltage range: 0.85V to 4.5V
  • 3.3V fixed or adjustable output
  • Integrated synchronous rectifier: 0.3Ω
  • 0.3Ω switch
  • Anti-ringing switch technology
  • Programmable inductor peak current
  • Logic shutdown control
  • Under voltage lock-out at 0.61V
  • Programmable low battery detect
  • Single or dual cell alkaline
  • Small 10-pin DFN package and industry standard 10-pin MSOP
