GreenChip III+ SMPS control IC

Rev. 1 — 21 April 2011

Product data sheet

1. General description

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

controller ICs. The SSL4101T combines a controller for Power Factor Correction (PFC)

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

LED lighting application 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 off to maintain high efficiency.

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 SSL4101T is a MultiChip Module, (MCM), containing two chips. The proprietary high

voltage BCD800 process which makes direct start-up possible from the rectified universal

mains voltage in an effective and green way. The second low voltage SiIlicon On Insulator

(SIO) is used for accurate, high speed protection functions and control.

The SSL4101T enables extremely efficient and reliable LED lighting application power

supplies with power requirements from 10 W to 300 W, to be designed easily and with a

minimum number of external components.

The new SSL4101T allows a typical 150 W LED lighting application power supply

(universal input, 48 V (DC) output, TEA1761T on the secondary side for Synchronous

Rectification) to achieve the following performances at full load:

• 120 V (AC): 92 % efficiency, 0.998 PF, 5.8 % THD, < 190 mW standby power

• 277 V (AC): 94 % efficiency, 0.978 PF, 9 % THD, < 350 mW standby power

1.1 Industry standard THD, low standby input power and high-efficiency

The SSL4101T enables LED lighting application power supplies to achieve the industry

standard of < 20 % THD for the input current at full load and all nominal input voltages:

100 V (AC), 120 V (AC), 230 V (AC), 240 V (AC) and 277 V (AC).

• Extremely low input power in Standby mode eliminates the need for an additional

housekeeping power supply to power the lighting controllers/dimmers.
