LT3498EDDB

IC LED DRVR RGLTR PWM 20MA 12DFN

Manufacturer: Analog Devices Inc.

Categories: LED Drivers

Quality Control: Learn More

Analog Devices Inc. LT3498EDDB is a single-output DC-DC boost LED driver IC. This component features an internal switch and supports both analog and PWM dimming for precise control of LED output current, up to 20mA. Operating with a fixed frequency of 2.3MHz, it efficiently converts input voltages from 2.5V to 12V to an output voltage of up to 32V. The LT3498EDDB is housed in a 12-DFN (3x2) package for surface mounting, with an exposed pad for improved thermal performance. Its compact design and robust regulation capabilities make it suitable for backlight applications. 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.
