ANALOG DEVICES LTC3115MPFE-1#PBF DC-DC Switching Synchronous Buck-Boost Regulator, Adjustable, 2.7V-40V in, 2.7V-40V out, TSSOP-EP-20

LTC3115MPFE-1#PBF is a high-voltage monolithic synchronous buck-boost DC/DC converter. Its wide 2.7V to 40V input and output voltage ranges make it well-suited to a wide variety of automotive and industrial applications. A proprietary low-noise switching algorithm optimizes efficiency with input voltages that are above, below or even equal to the output voltage and ensures seamless transitions between operational modes. Programmable frequency PWM mode operation provides low noise, high efficiency operation and the ability to synchronize switching to an external clock. Switching frequencies up to 2MHz are supported to allow use of small value inductors for miniaturization of the application circuit. Applications include 24V/28V industrial applications automotive power systems, telecom, servers and networking equipment, fire-wire regulator, multiple power source supplies.
