LT3120JV#PBF

LT3120 is a high efficiency 26V monolithic buckboost 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. It is used in application such as RF power supply, USB power delivery, system backup power supply, 1-cell to 5-cell lithium battery powered products, wide input range power supply, lead acid to 12V regulator etc.
