The Analog Devices Inc. LTC3523EUD-2-PBF is a dual, synchronous buck-boost switching regulator. This versatile component integrates two independent regulators, each capable of delivering 400mA and 600mA (switch current) respectively, from a single IC. Operating with an input voltage range of 1.8V to 5.5V, it supports adjustable positive output voltages from 0.615V up to 5.5V. The device features a high switching frequency of 2.4MHz, enabling the use of small external components and contributing to efficient power conversion. Its buck-boost topology allows it to regulate output voltages that are higher, lower, or equal to the input voltage. The LTC3523EUD-2-PBF is supplied in a 16-lead 3x3mm QFN package with an exposed pad for improved thermal performance, suitable for surface mount applications. This component finds application in portable electronics, battery-powered devices, and power management systems.
