• Description: Greenchipii Smps Control Ic
• Manufacturer: NXP Semiconductors

Philips Semiconductors
GENERAL DESCRIPTION
The GreenChip II is the second generation of green
Switched Mode Power Supply (SMPS) controller 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 reduced frequency and with valley detection.

PACKAGE
If burst mode operation is applied, the standby power level
can even be reduced to below 1 W.
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, reliable supplies can easily be designed
using the GreenChip II controller.
