LTC3115IDHD-2#PBF

LTC3115-2 is a high voltage monolithic synchronous buck-boost DC/DC converter optimized for applications subject to fast (<lt/>1ms) input voltage transients. This device is well suited for use in a wide variety of automotive and industrial power supplies. 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 upto 2MHz are supported to allow use of small value inductors for miniaturization of the application circuit. It is widely used in application such as 24V/28V industrial applications, automotive power systems, telecom, servers and networking equipment, firewire regulator, multiple power source supplies etc.
