TEA1750

GreenChip III SMPS control IC

Rev. 02 — 15 December 2008

Product data sheet

1. General description

The GreenChip III is the third generation of green Switched Mode Power Supply (SMPS)

controller ICs. The TEA1750 combines a controller for Power Factor Correction (PFC) and

a ﬂyback controller. Its high level of integration allows the design of a cost-effective power

supply with a very low number of external components.

The special built-in green functions provide high efﬁciency at all power levels. This applies

to quasi-resonant operation at high power levels, quasi-resonant operation with valley

skipping, as well as to reduced frequency operation at lower power levels. At low power

levels, the PFC switches over to burst mode control to maintain high efﬁciency. In burst

mode, soft-start and soft-stop functions are added to eliminate audible noise.

During low power conditions, the ﬂyback controller switches to frequency reduction mode

and limits the peak current to 25 % of its maximum value. This will ensure high efﬁciency

at low power and good standby power performance while minimizing audible noise from

the transformer.

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

Silicon On Insulator (SOI) IC is used for accurate, high speed protection functions and

control.

The TEA1750 enables highly efﬁcient and reliable supplies with power requirements up to

250 W, to be designed easily and with the minimum number of external components.

2. Features

2.1 Distinctive features

I Integrated PFC and ﬂyback controller

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

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

cost-effective design

2.2 Green features

I On-chip start-up current source

2.3 PFC green features

I Valley/zero voltage switching for minimum switching losses (patented)

I Frequency limitation to reduce switching losses

I Burst mode operation if a low load is detected at the ﬂyback output (patented)
