Besides efficiency and current accuracy, the main features in highest demand for DC-DC LED driver ICs are analog and PWM dimming and thermal protection of the LED system. Despite the high efficiency of LEDs, it is important to remember that nearly 60% of all energy supplied to LEDs converts to heat. Exposure to high temperatures significantly decreases LEDs’ lifetime, eliminating a key value proposition for purchasing an LED fixture. The value proposition from Infineon LED driver IC’s is a gradual reduction of the LED current which increases the lifetime and reliability of the LED system.
