The LTC3130IUDC-1#PBF is a high-efficiency, synchronous buck-boost DC/DC converter from Analog Devices Inc., designed to regulate output voltages above, below, or equal to the input voltage. With a wide input range of 1.8V to 5.5V, it is suitable for single cell Li-Ion/Polymer, or multicell alkaline/NiMH applications. This versatility makes it an ideal choice for portable battery-powered devices where the input voltage can vary significantly as the battery discharges.

Featuring a proprietary 4-switch buck-boost topology, the LTC3130IUDC-1#PBF provides a seamless transition between buck and boost modes, ensuring a consistent output regardless of the input voltage conditions. This converter can deliver up to 600mA of continuous output current at a fixed output voltage of 1.8V or can be programmed via an external resistor from 0.6V to 5.5V, offering flexibility for a wide range of applications.

The LTC3130IUDC-1#PBF incorporates low R<sub>DS(ON) internal switches that enable efficiencies up to 95%, contributing to extended battery life in portable applications. Additionally, the device features Burst Mode® operation, which reduces quiescent current to only 1.6µA, further improving battery life during light load conditions.

With its robust feature set, which includes soft-start to limit inrush current during startup, thermal protection, and a power good indicator, the LTC3130IUDC-1#PBF is a highly reliable solution for demanding applications. It also offers true output disconnect in shutdown and inrush current limiting, making it a safe choice for systems sensitive to high startup currents.

Encased in a compact, 16-lead QFN package, the LTC3130IUDC-1#PBF is designed for space-constrained applications. Its small footprint and low profile make it a perfect fit for handheld devices, medical equipment, and other portable electronics that require efficient power management.

Analog Devices Inc. is known for its high-quality, precision components, and the LTC3130IUDC-1#PBF is no exception, offering performance and reliability for a wide array of power conversion needs.
