S-8460 Key Features
- Single-coil, step-up or step-down switching realizes high efficiency
- High efficiency is realized by using only N-channel power MOS FET as an external power MOS
- Synchronous rectification at step-down operation
- Input voltage
- Variable output voltage
- Automatic-recovery overload protection circuit
- Oscillation frequency
- Soft-start function set by an external capacitor (CSS)
- Shutdown function
- Lead-free products
