RichTek Technology Corporation PMIC - PMIC - LED Drivers - RT8575GQW RT8575GQW

The RT8575GQW is a high-efficiency LED driver designed for LCD panels utilizing an array of LEDs for backlighting. It supports a wide input voltage range from 4.2V to 24V and can drive up to four LED strings in parallel, with each string capable of supporting up to 18 LEDs. The device provides adjustable LED current from 50mA to 150mA, with a typical current accuracy and matching of ±1%, ensuring uniform brightness across the LED strings. The integrated boost controller features a maximum output voltage of 60V and includes cycle-by-cycle overcurrent protection. The RT8575GQW also supports PWM dimming with a frequency range of 120Hz to 1kHz, allowing for precise control of LED brightness without inrush current issues. The switching frequency can be adjusted between 150kHz and 500kHz, enabling a balance between efficiency and component size. This product is available in WDFN-16L 5x5 and DIP-16 packages, making it suitable for various PCB layouts. It is RoHS compliant and halogen-free, meeting current environmental standards. The RT8575GQW is ideal for applications requiring reliable and efficient LED driving solutions.
