SY7070A Overview
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
