Description

General part information

LT3120 Series

The LT3120 is a high efficiency 26V monolithic buck-boost converter. Extensive feature integration and very low resistance internal power switches minimize the total solution footprint for even the most demanding applications. A proprietary 4-switch PWM architecture provides seamless low noise operation from input voltages above, equal to, or below the output voltage.External frequency programming as well as synchronization using an internal PLL enable operation over a wide switching frequency range of 400kHz to 2MHz. The wide 2.5V to 26V input range is well suited for operation from unregulated power sources including battery stacks and backup capacitors. After start-up, operation is possible with input voltages as low as 500mV.Other features include, output short-circuit protection, thermal overload protection, less than 3μA shutdown current, power good indicator, Burst Mode operation, and maximum power point control.The LT3120 is offered in thermally enhanced 28-lead 4mm × 5mm LQFN package.APPLICATIONSRF Power SupplyUSB Power DeliverySystem Backup Power Supply1-Cell to 5-Cell Lithium Battery Powered ProductsWide Input Range Power SupplyLead Acid to 12V Regulator
