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.
