TEA1530T/AT/AP
GreenChip II SMPS control IC
Rev. 01 — 30 June 2008
Product data sheet
1. General description
The GreenChip II is the second generation of green Switched Mode Power Supply
(SMPS) controller ICs. Its high level of integration allows the design of a cost effective
power supply with a very low number of external components.
The TEA1530(A) (TEA1530T, TEA1530AT and TEA1530AP) can be used in fixed
frequency converter designs for low voltage, high current applications. At low power
(standby) levels, the system operates in cycle skipping mode which minimizes the
switching losses during standby.
The proprietary high voltage BCD800 process makes direct start-up possible from the
rectified universal mains voltage in an effective and green way. A second low voltage
BICMOS IC is used for accurate, high speed protection functions and control.
The TEA1530(A) enables highly efficient and reliable supplies to be designed easily.

7. Functional description
The TEA1530(A) is the controller of a compact flyback converter, with the IC situated at
the primary side. An auxiliary winding of the transformer powers the IC after start-up;

Cycle skip and FF-CCM operation
Because of the fixed frequency mode, the internal oscillator determines the start of the
next converter stroke.
A cycle skipping mode is activated at very low power (standby) levels.
