LM2753SD

IC LED DRV RGLTR PWM 10WSON

Manufacturer: National Semiconductor

Categories: LED Drivers

Quality Control: Learn More

National Semiconductor LM2753SD is a high-efficiency, single-output DC-DC regulator utilizing a switched capacitor (charge pump) topology. This LED driver IC is designed for applications requiring precise illumination control, featuring integrated PWM dimming capabilities. With an internal switch, it supports a maximum output current of 400mA, ideal for camera flash functionalities. Operating at a frequency of 725kHz, it is housed in a compact 10-WSON (3x3) package, suitable for surface mount applications. The device accepts a supply voltage range of 3V to 5.5V, delivering a regulated output voltage between 4.75V and 5.25V. Its robust design allows for operation across an industrial temperature range of -40°C to 85°C. This component is frequently specified in portable electronics and mobile devices where efficient LED illumination is critical.

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.
