Analog Devices Inc. LTC3119IUFD#PBF - Efficient Power Conversion for Demanding Applications

The LTC3119IUFD#PBF is a versatile, high efficiency, multi-chemistry synchronous buck-boost converter from Analog Devices Inc. Designed to manage power supply requirements in a wide array of electronics, this converter is capable of delivering up to 5A of continuous output current. Its wide input voltage range of 2.5V to 18V and output voltage range of 0.8V to 18V make it suitable for applications operating on multiple or variable power sources, including single-cell Li-Ion to multi-cell battery stacks, solar panels, supercapacitors, and wall adapters.

This advanced power solution features proprietary buck-boost PWM control circuitry, which allows for a seamless transition between buck and boost modes without significant disruption in performance. This ensures a stable output voltage even when the input voltage crosses over the output voltage, making the LTC3119IUFD#PBF an ideal choice for applications that demand a stable power supply under varying input conditions.

The device's high efficiency is maintained over a broad range of load currents by utilizing a low loss switching algorithm, which significantly reduces heat generation and improves system longevity. The LTC3119IUFD#PBF also integrates programmable input current limit, which protects the source supply and the converter from overcurrent conditions. Furthermore, its adjustable switching frequency, which can be set from 400kHz to 2MHz with an external resistor, allows designers to optimize the size of external components and accommodate space-constrained applications.

For enhanced flexibility, the LTC3119IUFD#PBF includes selectable Burst Mode® operation for improved efficiency at light loads and a 1μA shutdown feature that extends battery life in portable devices. The device is packaged in a compact 24-lead QFN package (4mm x 5mm), which is RoHS compliant and designed for thermally efficient operation.

Whether you're designing portable battery-powered electronics, automotive power supplies, or industrial equipment, the LTC3119IUFD#PBF from Analog Devices Inc. offers a powerful, flexible, and efficient solution to meet your stringent power conversion needs.
