NXP TEA1751T GreenChip III SMPS control IC New in stock

NXP TEA1751T GreenChip III SMPS control IC New in stock

Distinctive features

„ Integrated PFC and flyback controller.

„ Universal mains supply operation (70 V (AC) to 276 V (AC)).

„ Dual boost PFC with accurate maximum output voltage (NXP patented).

„ High level of integration, resulting in a very low external component count and a 

cost-effective design.

Green features

„ On-chip start-up current source

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.

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.

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).
