3114FE-1

Product Overview

3114FE-1 is commonly associated with Analog Devices / Linear Technology LTC3114FE-1 series, a 40V 1A synchronous buck-boost DC/DC converter with programmable average output current. The device is designed to regulate output voltage when the input voltage is above, below or equal to the output voltage, making it useful for wide-input power systems and battery-powered equipment. With synchronous rectification, low-noise buck-boost PWM control, current-mode operation, programmable output current limit and TSSOP package options, it is suitable for industrial power supplies, automotive auxiliary power rails, battery-powered systems, distributed power architectures, backup power circuits and embedded power boards.
