TEA1752T; TEA1752LT
GreenChip III SMPS control IC
Rev. 02 — 24 June 2010
Product data sheet
1. General description
The GreenChip III is the third generation of green Switched Mode Power Supply (SMPS)
controller ICs. The TEA1752T and TEA1752LT combine 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.
During low power conditions, the flyback controller switches to frequency reduction mode
and limits the peak current to an adjustable minimum value. This will ensure high
efficiency at low power and good standby power performance while minimizing audible
noise from the transformer.
The TEA1752(L)T is a MultiChip Module (MCM), containing two chips. The proprietary
high voltage BCD800 process which enables direct start-up from the rectified universal
mains voltage in an effective and green way and a low voltage Silicon-On Insulator (SOI)
which provides accurate, high speed protection functions and control.
The TEA1752(L)T 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.
