NXP Semiconductors
TEA1751T; TEA1751LT
GreenChip III SMPS control IC
2.3  PFC green features
Valley/zero voltage switching for minimum switching losses (NXP patented).
Frequency limitation to reduce switching losses.
PFC is switched off when a low load is detected at the flyback output.
2.4  Flyback green features
Valley switching for minimum switching losses (NXP patented).
Frequency reduction with fixed minimum peak current at low power operation to
maintain high efficiency at low output power levels.
2.5  Protection features
Safe restart mode for system fault conditions.
Continuous mode protection by means of demagnetization detection for both
converters (NXP patented).
UnderVoltage Protection (UVP) (foldback during overload).
Accurate OverVoltage Protection (OVP) for both converters (adjustable for flyback
converter).
Mains voltage independent OverPower Protection (OPP)
Open control loop protection for both converters. The open loop protection on the
flyback converter is latched on the TEA1751L and safe restart on the TEA1751.
IC overtemperature protection.
Low and adjustable OverCurrent Protection (OCP) trip level for both converters.
General purpose input for latched protection, e.g. to be used for system
OverTemperature Protection (OTP).
3.   Applications
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.
