    Products Detail

    The RT8555 is a high efficiency boost converter with I2C controlled 6-channel LED driver. It features wide operating input voltage (2.7V to 24V), high output voltage up to 36V, programmable channel current (10mA to 35mA) with ±3% accuracy and ±2% matching. The device supports direct PWM dimming up to 20kHz and PWM to analog dimming with 8-bit resolution. It includes internal current sinks, I2C interface for controlling dimming mode, operating frequency, and LED current. The internal 100mΩ, 36V power switch with current-mode control provides over-current protection. Switching frequency is adjustable from 300kHz to 2MHz for flexibility between efficiency and component size. Protections include LED strings open detection, current limit, programmable over voltage protection, and over-temperature protection. Available in WL-CSP-20B 1.65 x 2.05 package with 0.4mm pitch.
