TEA1755T/1规格书详情
General description
The GreenChip is the latest generation of green Switched Mode Power Supply (SMPS)
controller ICs. The TEA1755T combines a controller for Power Factor Correction (PFC)
and a flyback controller. Its high level of integration enables cost-effective power supply
design using a very low number of external components.
The PFC operates in Quasi-Resonant (QR) or Discontinuous Conduction Mode (DCM),
with valley switching.
The specially built-in green functions provide high efficiency at all power levels. At high
power levels the flyback operates in QR mode or DCM with valley detection. At medium
power levels, the flyback controller switches to Frequency Reduction (FR) mode and limits
the peak current to an adjustable minimum value. In low power mode, the PFC switches
off to maintain high efficiency. At very low power levels, when the flyback switching
frequency drops below 25 kHz, the flyback converter switches to burst mode. During the
non-switching phase of burst mode, the internal IC supply current is minimized to further
optimize efficiency. Valley switching is used in all operating modes.
The advanced burst mode ensures high-efficiency at low power and good standby power
performance while minimizing audible transformer noise.
The TEA1755T is a Multi-Chip Module, (MCM), containing two chips. The proprietary
high-voltage BCD800 process 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 TEA1755T enables easy design of highly efficient and reliable supplies up to 250 W.
These power supply designs are cost-effective, requiring the minimum number of external
components.
Remark: All values in this document are typical values unless otherwise stated.
