1. Introduction
WARNING
Lethal voltage and fire ignition hazard
The non-insulated high voltages that are present when operating this product, constitute a
risk of electric shock, personal injury, death and/or ignition of fire.
This product is intended for evaluation purposes only. It shall be operated in a designated test
area by personnel qualified according to local requirements and labor laws to work with
non-insulated mains voltages and high-voltage circuits. This product shall never be operated
unattended.
This document explains the basic operation and application of the 150 W SSL4101
Solid-State Lighting (SSL) driver evaluation board. The device is designed to meet the
requirements of universal mains SSL drivers used in industrial and commercial lighting
applications. Both Constant Current Mode (CCM) or Constant Voltage Mode (CVM)
outputs are supported over power ranges from 100 W to 280 W delivered to the load with
minor modifications.
The SSL4101 uses NXP Semiconductors GreenChip III+ Switched Mode Power Supply
(SMPS) controller IC technology. The SSL4101 combines a controller for Power Factor
Correction (PFC) and a flyback controller. The SSL4101’s high level of integration allows
design of a cost-effective LED lighting applications in a small form factor using low
number of components.
Remark:
In this user manual, all voltages are in V (AC) unless otherwise specified.

2. Safety warning
The board can be connected to a mains voltage between 108 V and 305 V. A different
mains voltage range can be selected with minor modifications. The output connected to
the LEDs is designed for reinforced isolation from the mains. The demo board is designed
to meet UL1950, UL8750 and EN61347 but was not submitted for safety compliance.
Touching the reference board during operation must be avoided at all times.
An isolated housing for the board and the LED's is mandatory when used in uncontrolled,
non-laboratory environments. Therefore the board must be connected to the mains supply
via a galvanic isolated (variable) transformer. These devices can be recognized by the
symbols shown in
Figure 2.

4. SSL4101 driver overview
The SSL4101 is part of NXP Semiconductors GreenChip III+ (third generation) of green
Switched Mode Power Supply (SMPS) controller ICs. The SSL4101T combines both a
controller for Power Factor Correction (PFC) and a flyback controller. The integrated
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 the SSL4101’s 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 ensures 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 SIlicon 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 using the
minimum number of additional components.
