SY7070A - 100mA Maximum Output Current Synchronous Boost

Download the SY7070A datasheet PDF. This datasheet also covers the SY7070 variant, as both devices belong to the same 100ma maximum output current synchronous boost family and are provided as variant models within a single manufacturer datasheet.

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.
