The LTC3111HMSE#PBF from Analog Devices is a fixed-frequency, synchronous buck-boost DC/DC converter designed for applications requiring seamless operation from input voltages above, below, or equal to the output voltage. It features a wide input and output range of 2.5V to 15V and can deliver up to 1.5A of continuous output current.
Key electrical specifications include an 800kHz switching frequency, selectable PWM or Burst Mode operation for high efficiency across various load conditions, and a low 49µA quiescent current in Burst Mode. The converter also includes an accurate RUN pin for programming the turn-on threshold, short-circuit protection, internal soft-start, and thermal shutdown.
This device is well-suited for a variety of power source applications, including single or multiple-cell batteries and wall adapters. It is available in a small, thermally enhanced 16-lead MSOP package with an exposed pad, suitable for surface mount applications.
The LTC3111HMSE#PBF supports adjustable output voltage and utilizes a 4-switch, single-inductor architecture, contributing to its low noise and efficient performance.
