A CMOS low-power SoC for HID and LED lamps ballast

摘要

In this work a new concept of hybrid lamps burner is presented. The High Intensity Discharge (HID) lamps and the new generation Light Emitting Diodes (LED) lamps can be driven by the same electronic ballast using this hybrid ASIC in 0.35µm CMOS technology. In the state-of-art the electronic ballasts are managed by powerful general-purpose devices (usually FPGA or microcontroller). These devices are not customized for the specific application. Thus they have a larger area occupation and power consumption compared to ASIC solution. The designed ASIC power consumption is 35 mW and the package area is about 6.5 cm² against 550 mW and 6.5 cm² for commonly used PIC 18FXX2.
