GreenChipII SMPS control IC
Rev. 01 — 28 May 2004
Preliminary 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 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 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
s Undervoltage protection (foldback during overload)
