lamps offer the vehicles a touch of individual styling.
Ef?cient LED Control
LEDs must be driven with a source of constant current.
Most LEDs have a speci?ed current level that will achieve
the maximum brightness for that LED without premature
failures. An LED could be driven with a linear voltage
regulator con?gured as a constant current source.
However, this approach is not practical for higher power
LEDs due to power dissipation in the regulator circuit. A
switch-mode power supply (SMPS) provides a much more
ef?cient solution to drive the LED. SMPS implementation
with Microchip products can be analog, digital or mixed
signal based solutions.
An LED will have a forward voltage drop across its
terminals for a given current drive level. The power supply
voltage and the LED forward voltage characteristics
determine the SMPS topology that is required. Multiple
LEDs can be connected in series to increase the forward
voltage drop at the chosen drive current level.
The SMPS circuit topologies adopted to regulate current
in LED lighting applications are the same used to control
voltage in a power supply application. Each type of SMPS
topology offers the system designer trade-offs as shown
in the table below.

Automotive Ambient Lighting Module
Reference Design ( APGRD004)
The Automotive Ambient Interior
Lighting Module Reference Design
demonstrates microcontroller-based
control of RGB LED devices. This
module can be controlled remotely
by a master body controller via a LIN bus. These
modules are offered in a very compact form-factor
board and are comprised of a PIC12F615 MCU, an
MCP2021 LIN transceiver/voltage regulator, and RGB
LED. LIN commands are interpreted by the module
to control color mixing (16,383 colors) and intensity
(1023 levels). The kit ships with 4?modules to assign
as lighting zones in a LIN or J2602 network. These
modules can also be used in conjunction with the
APGDT001 LIN Serial Analyzer to quickly create a
working LIN network straight out of the box.
