The Analog Devices Inc. LTC3521EUF-PBF is a versatile triple output switching regulator IC. This component features two independent buck converters capable of 600mA and 1A outputs, respectively, alongside a buck-boost converter with an adjustable output voltage from 0.6V up to 5.5V. Operating with an input voltage range of 1.8V to 5.5V, the LTC3521EUF-PBF utilizes a 1.1MHz switching frequency. Its synchronous rectification design enhances efficiency, making it suitable for power management in portable electronics, battery-powered devices, and industrial control systems. The device is housed in a 24-WFQFN exposed pad package for surface mounting and operates across a temperature range of -40°C to 125°C.
