Adapt DC Voltage To Perform PWM DImming Of High-Brightness LEDs
High-brightness LEDs (HBLEDs) are making inroads into more traditional lighting applications that include a dc distribution system (for example, 24-V MR-16 track lights). HBLEDs are more efficient, and they have a potentially longer lifespan than do halogen or xenon lamps. Because hysteretic controllers are inexpensive, simplify lighting designs, and require no compensation networks, they’re well-suited for driving HBLEDs....

Speed Control Handles Isolated –48-V Fans
Chips are available to monitor and control ventilation fans. But less common are fan controllers for telecom applications. Such fans must operate in electrically isolated environments with a supply voltage in the 36- to 72-V range. For example, the...
