GENERAL DESCRIPTION
The GreenChip
Switched Mode Power Supply (SMPS) control ICs
operating directly from the rectified universal mains. A high
level of integration leads to a cost effective power supply
with a very low number of external components.
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 at a reduced frequency and with valley detection.

DESCRIPTION
The proprietary high voltage BCD800 process makes
direct start-up possible from the rectified mains voltage in
an effective and green way. A second low voltage
BICMOS IC is used for accurate, high-speed protection
functions and control.
Highly efficient and reliable supplies can easily be
designed using the GreenChipII control IC.
