Session Introduction (1/2)<br />
• Multiple loads like lamps, light emitting diodes (LEDs), etc.<br />
• Load protection<br />
� LEDs and bulbs are very sensitive components<br />
Requiring current and voltage control to achieve specified lifespan<br />
� LEDs are ‘current-driven’<br />
Emitted light depends on amount of current<br />
Variation in power supply requires current adjustment<br />
• Sophisticated pulse width modulation (PWM) generation<br />
• Advanced diagnostics<br />
• Unified system for lamp as well as for LED control<br />
TM
►The ideal system support?<br />
• Requires intelligent microcontroller hardware<br />
No CPU load<br />
Diagnosis sync with PWM<br />
Inrush current control<br />
Optimized design for EMC<br />
