Summary
Microchip’s Digital LED Lighting Development Kit
(DM330014) enables designers to quickly leverage the
capabilities and performance of the dsPIC33 ‘GS’ series
of Digital Signal Controllers (DSCs), to develop LED lighting
products. The dsPIC33 ‘GS’ DSC and this reference design
allow developers to create a 100% digitally controlled ballast
function, while including advanced features such as dimming
and color hue control. The dsPIC33 ‘GS’ DSCs can support
an entire system implementation for LED lighting products,
including power-conversion circuits, such as AC-to-DC and
DC-to-DC conversion, along with functions such as Power
Factor Correction (PFC), which are necessary for a complete
product and lower the overall system cost.
Benefits offered by the digital-power techniques in
this reference design and the dsPIC33 ‘GS’ series of
DSCs include:

Summary
In recent years, High Intensity Discharge (HID) lamps have
been accepted as a good lighting source for automotive
headlight applications. However, the startup process of an
automotive HID lamp is complex. It consists of six stages
and each stage presents different characteristics, which
need different control strategies. A digitally controlled ballast
has many advantages over the traditional analog approach.
