- Anti-clipping Function (ACF)
- Power Limit (PLIMT) function that can be used to clip the output voltage level below the supply rail
- Spread Switching Frequency, Inductor-free Operation
- Differential / Single-ended Analog Input
- Integrated Self-protection Circuits Including, Undervoltage, Overtemperature, and Overcurrent
- LF and HF Package of ETSSOP28, EPAD up
