High Efficiency LED Smart Driver
9-13 volt systems easily adapt to a Smart Driver Circuit
to drive High Power LEDs using the MCP1702, MCP1652
and a PIC10F202. The MCP1702 directly connected to
the 12 volt source creates a 5 volt bias supply capable of
delivering 250 mA to the intelligent boost control circuit.
The LEDs are powered by the source voltage boosted by the
MCP1652, minimizing the current requirements for the 5V
power system. A PIC10F202 adds intelligence to the circuit
providing a means for thermal protection, load open and
short circuit protection as well as the capability of a user
interface to control dimming and other features.
Low Battery Detect enables the designer to determine
a trip point for a low battery condition to make “smart”
adjustments to the circuit function with the PIC10F202. The
Power Good Indication enables the designer to determine
when output voltage conditions are correct.
