Quality Control: Learn More
The Analog Devices Inc. LT3667IUDD is a versatile power management IC featuring a triple output configuration. This component integrates one synchronous step-down (buck) regulator and two linear low-dropout (LDO) regulators, offering a flexible solution for power sequencing and regulation. The buck converter operates with a switching frequency adjustable between 243kHz and 2.2MHz, supporting input voltages from 1.6V to 45V. It provides an output current of 400mA with an adjustable output voltage range. The two LDO outputs each deliver 200mA with an adjustable output voltage range, suitable for generating clean power rails. The LT3667IUDD is housed in a 24-QFN (3x5) package with an exposed pad for enhanced thermal performance, designed for surface mount applications and operating over an industrial temperature range of -40°C to 125°C. This component is commonly utilized in automotive, industrial, and battery-powered systems requiring efficient, multi-output voltage regulation.
