description/ordering information
The TLED2043 is a four-channel, white LED driver used for backlighting color LCD displays in portable
equipment. The device consists of four FET outputs, each of which is used essentially as a current sink to bias
a single LED. The gates of the FETs are controlled collectively by a current-control amplifier that automatically
monitors the battery voltage. If the battery voltage drops when compared to an externally set reference voltage,
the current-control amplifier proportionately lowers all four FETs
’
output drives to conserve battery power.
Additionally, the TLED2043 has internal switches that are programmed to disconnect the power supply and
supporting circuitry to the device when LED operation is not needed, offering significant power savings during
periods of inactivity.
Offering smaller board space, lower R
DS-ON
, and lower overall cost, the TLED2043 has clear advantages over
the use of discrete devices in implementing a white-LED driver solution. Compared to the use of charge pumps
and dc-dc converters in similar applications, the TLED2043 again can offer the advantages of smaller board
space and lower solution cost because no costly inductors and/or capacitors are required. In addition, it avoids
the switching-noise and power-loss issues associated with such devices.
