DESCRIPTION
KEY FEATURES
The LXMG2203 is a fully enclosed
compact solid-state LED lighting driver
module. It operates from a universal AC
input supply in the range of 100V_AC to
277V_AC, 50/60Hz to drive a string of LEDs
with active power factor correction. LED
string voltage can range from 14V to 48V
at a constant current of 700mA to drive a
wide variety of LED lamp string
requirements.
Control terminal leads include a
dimming input BRITE_A with a dedicated
RETURN lead. The amplitude of the
output LED string current will vary from
10% to 100% corresponding to a 1V_DC to
10V_DC signal on the BRITE_A input
following the 0V to 10V ESTA E1.3-2001
Analog Control Specification Standard.
The BRITE_A terminal when pulled down
below minimum dimming will turn off the
LEDs and enter a low power consumption
mode. A second control terminal lead
provides a FAULT indicator.
In the case that there is an LED string
short between OUT(+) and OUT(-), or
string open, or a product over temperature
condition the FAULT terminal will go
low. The FAULT terminal includes an
open collector device that can be pulled up
to a maximum of 48V and will sink 8mA
typical to 0.8V when a short or open fault
occurs.
To reduce audible noise the internal
switching frequency remains above
30kHz. Safety features include open
output circuit protection, whole string
short circuit protection. The maximum
allowable hot spot case temperature is
90°C (above this temperature the module
will be thermally self-protected). The
recommended operating ambient
temperature range is -30°C to 70°C, as
long as the maximum case temperature is
not exceeded. The compact enclosure is
rated to IP66, meets UL8750 and UL1310
class 2, CE pending.
