TEA1532BT; TEA1532CT
GreenChip II SMPS control IC
Rev. 01 — 18 January 2007
Product data sheet
1. General description
The GreenChip II is the second generation of controller ICs intended for green flyback
Switched Mode Power Supplies (SMPS). Its high level of integration allows the design of a
cost effective power supply with a very low number of external components.
The TEA1532BT; TEA1532CT can also be used in fixed frequency, Continuous
Conduction Mode (CCM) converter designs for low voltage and high current applications.
At low power (standby) levels the system operates in cycle skipping mode which
minimizes the switching losses during standby.
The special built-in green functions allow the efficiency to be optimum at all power levels.
This holds for quasi-resonant operation at high power levels, as well as fixed frequency
operation with valley switching at medium power levels. At low power (standby) levels, the
system operates in cycle skipping mode with valley detection.
The proprietary high voltage BCD800 process makes direct start-up possible from the
rectified universal mains voltage in an effective and energy efficient way. A second low
voltage, Bipolar CMOS (BICMOS) IC is used for accurate, high speed protection functions
and control.
The TEA1532BT; TEA1532CT enables highly efficient and reliable supplies to be
designed easily.
