Texas Instruments LM3311SQX-NOPB is a versatile positive adjustable output boost switching regulator IC. Designed for high-efficiency step-up conversion, it features an adjustable output voltage ranging from 1.263V up to 20V. This component supports an input voltage range of 2.5V to 7V and can deliver an output current of up to 2A at the switch. The LM3311SQX-NOPB operates with selectable switching frequencies of 660kHz and 1.28MHz, offering flexibility in power supply design. Packaged in a compact 24-WFQFN exposed pad (4x4mm), it is suitable for surface mount applications. Its robust operating temperature range of -40°C to 125°C (TJ) makes it ideal for demanding applications in the automotive, industrial, and consumer electronics sectors. The device utilizes a non-synchronous boost topology.
