Manufacturer: Microchip Technology

Categories: LED Drivers

Quality Control: Learn More

The Microchip Technology MIC3291-18YD6-TR is a highly efficient, single-output DC-DC boost LED driver. This device features integrated switching capability with a maximum output current of 1.2A, enabling it to drive high-brightness LEDs. Its single-wire dimming interface provides precise control over LED brightness. Operating at a fixed frequency of 1.2MHz, the MIC3291-18YD6-TR utilizes a step-up (boost) topology and is housed in a compact TSOT-23-6 package, suitable for surface-mount applications. The device operates from a minimum supply voltage of 2.5V up to a maximum of 6.5V, with an operating temperature range of -40°C to 125°C. This component is commonly employed in backlight applications for portable electronics and displays where space and power efficiency are critical. The product is supplied in Tape & Reel packaging.

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.
