- Integrated PFC and flyback controller
- Universal mains supply operation between 90 V (AC) to 305 V (AC)
- High level of integration, results in cost-effective designs with very low external component counts
- On-chip start-up current source
- Power-down functionality for very low standby power
- Valley/Zero-Voltage Switching (ZVS) for minimum switching losses
- Frequency limitation reduces switching losses
- PFC switched off when a low-load is detected at the flyback output
- Valley/Zero-Voltage Switching (ZVS) for minimum switching losses
- Frequency limitation reduces switching losses
- PFC switched off when a low-load is detected at the flyback output
- Valley switching for minimum switching losses
- Frequency reduction with adjustable minimum peak current at low-power operation maintains high-efficiency at low output power levels
- Safe restart mode for system fault conditions
- UnderVoltage Protection (UVP)
- Accurate OverVoltage Protection (OVP)
- Mains voltage independent OverPower Protection (OPP)
- Open control loop protection for both converters
- OverTemperature Protection (OTP)
- Low and adjustable OverCurrent Protection (OCP) trip level for both converters
- General-purpose input for latched protection
