- Burst mode for low standby power consumption, meeting EuP Lot 6
- Frequency jitter to reduce EMI signature
- X-cap discharge function
- Adjustable overpower pensation
- Internal high-voltage current source
- VCC under-voltage lockout with hysteresis
- Brown-out protection on HV
- Overload protection with programmable
