The RT8450BGQW is a high voltage multi-topology LED driver capable of operating in buck, boost, or buck-boost configurations. It supports an input voltage range from 4.5V to 40V and can output up to 50V, making it suitable for various LED driving applications. The device features a 1.5A switch current and operates at switching frequencies of 800kHz or 500kHz, allowing for the use of smaller external components. Dimming can be achieved through analog or PWM signals, with a built-in mechanism for converting PWM to analog dimming using a single external capacitor. Additional features include programmable soft-start, over-voltage protection, under-voltage lockout, and thermal shutdown, ensuring safe operation. The RT8450BGQW is available in TSSOP-16 (Exposed Pad) and WDFN-12L 3x3 packages, and is compliant with RoHS and halogen-free standards.
