AMG-LL7AXX
Family of HV LED Driver Modules
1. Functional Description of the AMG-LL7AXX
The AMG-LL7AXX is a famiy of non isolated High Voltage LED driver modules. The family
consists out of a master and slave modules. A complete system can consist out of 1 master
and up to 2 LL7A7-9 (1500mA) or 4 LL7A4-6 (700mA) or 8 LL7A1-3 (350mA) slave modules.
The modules can be stacked up to form a line, a stack, a curve or other shapes. For all
shapes other than the line an interconnection cable is necessary. A 0-10V dimmer, analog
voltage or potentiometer can be connected to the master module for dimming. The modules
will go into low power shut down mode at dimming voltages below 1.2V.
Each Module has two shunt resistors, which allow for further adjustment of the LED current.
The nominal current will be supported by two shunt resistors. This is the factory setting. By
removing one of the shunts, the maximum LED current will be reduced.

3.2. Application Notes
The module can be operated directly off the mains. As such, all applicable safety rules and
guidelines have to be observed. Specifically, but not limited, during test and evaluation.
Warning, High Voltage!
Caution, exposed voltage on the circuit board. Working with line voltage is dangerous!
Electrical shock above 42V can be life threatening! Use only under the supervision of
qualified personnel! Caution, use only in a laboratory environment! Ensure all
applicable safety regulations are observed.

d) Modification of max. string current
the maximum string current is set by two shunt resistors on the slave modules. The two
shunts are in parallel and combined provide the highest current setting for the board.
Removing either one will lower the maximum string voltage of that particular slave
module.

One shunt on the slave boards can be removed with a soldering iron to further reduce
the maximum string current if desired.
e) Dimming...
A 0-10V dimmer can be attached to the master module. Both linear and logarithmic
dimming curves will work. Logarithmic dimming curves usually are more appealing to the
eye. Care needs to be taken, that the dimmer is connected with it's positive and negative
connectors correctly to the master module. It is also possible to connect a 3k
potentiometer or a galvanically isolated 0-10v source instead of a dimmer. All slave
modules which are connected to that particular master module will all simultaneously be
dimmed from that one connected dimmer. If the dimming input is left open, the slave
modules will work with their highest current setting. No open ended wires should be
connected to the dimmer input of the master module. Wiring from the master module to
the dimmer should not run parallel to mains lines. This can cause flicker, particularly at
the lower dimming end.
High voltage (>15V) provided to the dimmer connector will potentially destroy the master
and all connected slave modules.

13. Notes and Cautions
13.1. ESD Protection
The Requirements for Handling Electrostatic Discharge Sensitive Devices are described in the
JEDEC standard JESD625-A. Please note the following recommendations:
 When handling the device, operators must be grounded by wearing a for the purpose
designed grounded wrist strap with at least 1MΩ resistance and direct skin contact.
 Operators must at all times wear ESD protective shoes or the area should be
surrounded by for ESD protection intended floor mats.
 Opening of the protective ESD package that the device is delivered in must only occur at
a properly equipped ESD workbench. The tape with which the package is held together
must be cut with a sharp cutting tool, never pulled or ripped off.
 Any unnecessary contact with the device or any unprotected conductive points should be
avoided.
 Work only with qualified and grounded tools, measuring equipment, casing and

workbenches.
 Outside properly protected ESD-areas the device or any electronic assembly that it may
be part of should always be transported in EGB/ESD shielded packaging.
13.2. Storage conditions
The AMG-LL7AXX corresponds to moisture sensitivity classification ML2 , according to
JEDEC standard J-STD-020, and should be handled and stored according to J-STD-033.
