- Input operating voltage range of 3V to 20V
- Continuous inductor DCR or shunt resistor current sensing
- 0.6V ±1% reference (-40°C to 125°C junction temperature)
- Output voltage as high as 95% of input voltage
- Integrated MOSFET drivers
- Internal LDO bias supply
- External clock synchronization
- Adjustable soft-start with external capacitor
- Pre-biased startup capability
- Power supply tracking
- Input voltage feed-forward
- Power good indicator
- Precision enable with hysteresis
