LTC3119 - Linear

LTC3119 5A Synchronous Buck-Boost DC/DC Converter

The LTC®3119 is a high efficiency 18V monolithic buckboost converter that can deliver up to 5A of continuous output current. 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.
