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 TEA1532(A)P; TEA1532(A)T can also be used in ﬁxed frequency, Continuous

Conduction Mode (CCM) 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 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 green way. A second low voltage

BICMOS IC is used for accurate, high speed protection functions and control.

The TEA1532(A)P; TEA1532(A)T enables highly efﬁcient and reliable supplies to be

designed easily.

2. Features

2.1 Distinctive features

s Universal mains supply operation (70 V to 276 V AC)

s High level of integration, resulting in a very low external component count

s Fixed frequency Continuous Conduction Mode (CCM) operation capability

s Quasi-Resonant (QR) Discontinuous Conduction Mode (DCM) operation capability.

2.2 Green features

s Valley or zero voltage switching for minimum switching losses in QR operation

s Cycle skipping mode at very low loads; input power < 300 mW at no-load operation for

a typical adapter application

s On-chip start-up current source.

2.3 Protection features

s Safe restart mode for system fault conditions

s Zero current switch-on in QR mode
