SY7070 - 100mA Maximum Output Current Synchronous Boost

General Description

SY7070/A is a high efficiency, synchronous, current hysteresis control; step-up boost converter designed for single-cell or dual-cell alkaline, NiMH, or NiCd battery-powered applications.

It can convert down to 0.7V input voltage.

Key Features

  • 0.7V Minimum input voltage.
  • 5.5uA typical quiescent current.
  • Input under-voltage lockout.
  • Bypass function during shutdown.
  • Low RDS(ON) (main switch/synchronous switch) at output: 0.5/0.7ohm.
  • Fixed output voltage ﹣ SY7070: fixed 3.3V ﹣ SY7070A: fixed 3.0V.
  • Typical 350mA peak current limit.
  • Compact SOT23-5 package.
