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.
2. Features
2.1 Distinctive features
I Universal mains supply operation, 70 VAC to 276 VAC.
I High level of integration, resulting in a very low external component count.
I Fixed frequency operation.
2.2 Green features
I Cycle skipping mode at very low loads; input power < 300 mW at no-load operation for
a typical adapter application.
I On-chip start-up current source.
2.3 Protection features
I Safe restart mode for system fault conditions.
I Undervoltage protection (foldback during overload).
I IC OverTemperature Protection (OTP) (latched).
I Low and adjustable OverCurrent Protection (OCP) trip level.
I Soft (re)start.
I Mains voltage-dependent operation-enabling level.
I TEA1530AT and TEA1530AP: General purpose input for latched or safe restart
protection and timing, e.g. to be used for OverVoltage Protection (OVP), output short
circuit protection or system OTP.

Fig 4. 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.

Table 3: Limiting values …continued
In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured
with respect to ground (pin 2); positive currents flow into the chip; pin VCC may not be current driven.
The voltage ratings are valid provided other ratings are not violated; current ratings are valid
provided the maximum power rating is not violated.
