1. General description
2. Features
2.1 Distinctive features
2.2 Green features
2.3 Protection features
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 optimum efficiency at all power levels. This
applies to 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.
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.
Highly efficient, reliable supplies can easily be designed using the GreenChip II controller.

GreenChip II SMPS control IC
Rev. 01 — 3 July 2007
Universal mains supply operation (70 V AC to 276 V AC)
High level of integration, giving a very low external component count
Valley/zero voltage switching for minimum switching losses
Frequency reduction at low power standby for improved system efficiency (< 1 W)
On-chip start-up current source
Efficient quasi-resonant operation at high power levels
Cycle skipping mode at very low loads; input power < 300 mW at no-load operation for
a typical adapter application
Standby indication pin to indicate low output power consumption
Safe restart mode for system fault conditions
Continuous mode protection by means of demagnetization detection (zero switch-on
current)
Accurate and adjustable versatile Overvoltage Protection (OVP) (latched)
Short winding protection
Undervoltage protection (foldback during overload)
