TEA1752T

HV start-up DCM/QR flyback controller with integrated

DCM/QR PFC controller

Rev. 2 — 16 November 2012

Product data sheet

1. General description

The TEA1752T is the third generation of green Switched Mode Power Supply (SMPS)

controller ICs. The TEA1752T combines a controller for Power Factor Correction (PFC)

and a flyback controller. Its high level of integration allows the design of a cost-effective

power supply with a very low number of external components.

The special built-in green functions provide high efficiency at all power levels. This

efficiency applies to quasi-resonant operation at high-power levels, quasi-resonant

operation with valley skipping, as well as reduced frequency operation at lower power

levels. At low-power levels, the PFC switches off to maintain high efficiency.

During low-power conditions, the flyback controller switches to frequency reduction mode

and limits the peak current to an adjustable minimum value. This mode ensures high

efficiency at low-power and good standby power performance while minimizing audible

noise from the transformer.

The TEA1752T is a Multi-Chip Module, (MCM), containing 2 chips. The proprietary

high-voltage BCD800 process which makes direct start-up possible from the rectified

universal mains voltage in an effective and green way. The second low voltage

Silicon On Insulator (SOI) is used for accurate, high speed protection functions and

control.

The TEA1752T enables the design of highly efficient and reliable supplies with power

requirements of up to 250 W with a minimum number of external components.

Remark: All values provided throughout the running text, are typical values unless

otherwise stated.
