RT8555AWSC

IC LED DRV RGLTR PWM 20WLCSP

Manufacturer: Richtek USA Inc.

Categories: LED Drivers

Quality Control: Learn More

Richtek USA Inc. RT8555AWSC is a 6-output DC-DC boost LED driver IC designed for applications requiring precise backlight control. This device features a step-up (boost) topology with a selectable switching frequency range of 300kHz to 2MHz, allowing optimization for efficiency and component size. The RT8555AWSC supports both analog and PWM dimming for flexible brightness control, delivering up to 35mA per channel. Its internal switch capability simplifies design, and it operates from a supply voltage of 2.7V to 24V, with a maximum output voltage of 36V. Packaged in a compact 20-WLCSP (1.65x2.05) and supplied on tape and reel, this component is suitable for surface mount applications. It finds use in display backlighting across various electronic devices. The operating temperature range is -40°C to 85°C.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
