TLD5045EJ

Active and preferred

Device drives LEDs efficiently from higher voltage, regulates constant current for accuracy and lifespan. Integrated diode and transistor reduce external components and costs. Adjustable currents and frequency. Integrated PWM dimming enables LED dimming without a microcontroller. A pull-down transistor simulates current flow to prevent false open load detection. Ideal for decentralized light modules and avoiding BCM issues.
