Product Summary

The TEA1751T/N is a third generation of green Switched Mode Power Supply (SMPS) controller IC. The TEA1751T/N combines a controller for Power Factor Correction (PFC) and a flyback controller. The high level of integration facilitates the design of a cost-effective power supply using a minimum number of external components. The special built-in green functions provide high efficiency at all power levels. This applies to quasi-resonant operation at high power levels, quasi-resonant operation with valley skipping and reduced frequency operation at lower power levels. At low power levels, the PFC switches off to maintain high efficiency. The TEA1751T/N enables highly efficient and reliable supplies with power requirements of up to 250 W to be designed easily and with a minimum number of external components.

Parametrics

TEA1751T/N absolute maximum ratings: (1)current on pin PFCDRIVER, duty cycle < 10 %, IPFCDRIVER: -0.8 to +2 A; (2)current on pin HV, IHV: 5mA; (3)total power dissipation, Tamb < 75℃, Ptot: 0.6 W; (4)storage temperature, Tstg: -55 to +150℃; (5)junction temperature, Tj: -40 +150℃.

Features

TEA1751T/N features: (1)Integrated PFC and flyback controller; (2)Universal mains supply operation (70 V (AC) to 276 V (AC)); (3)Dual boost PFC with accurate maximum output voltage (NXP patented); (4)High level of integration, resulting in a very low external component count and a cost-effective design.
