Valley switching for minimum switching losses (patented)
Frequency reduction with fixed minimum peak current at low power operation to
maintain high efficiency at low output power levels
Safe restart mode for system fault conditions
Continuous mode protection by means of demagnetization detection for both
converters (patented)
UnderVoltage Protection (UVP) (foldback during overload)
Accurate OverVoltage Protection (OVP) for both converters (adjustable for flyback
converter)
Open control loop protection for both converters
IC OverTemperature Protection (OTP)
Low and adjustable OverCurrent Protection (OCP) trip level for both converters
Soft (re)start for both converters
Soft stop PFC to minimize audible noise
Mains UnderVoltage Protection (UVP)/ brownout protection
General purpose input for latched protection, e.g. to be used for system
Overtemperature protection
The device can be used in all applications that require an efficient and cost-effective
power supply solution up to 250 W. Notebook adapters in particular can benefit from
the high level of integration.
