- 4V to 14V input voltage range
- Internal high-side MOSFET with low RDS(ON) = 0.033Ω
- 300 kHz fixed frequency internal oscillator
- Low-side drive for synchronous operation
- Guaranteed less than 12 µA shutdown current
- Patented current sensing for current mode control
- Programmable soft-start
- Input undervoltage lockout
- Output overvoltage shutdown protection
