The LTC3118EUFD#PBF is a high-performance dual-input, synchronous buck-boost DC/DC converter from LT. It features an intelligent, integrated, low-loss PowerPath control, allowing it to efficiently operate from either input source to a programmable output voltage that can be above, below, or equal to the input voltage. With an input voltage range of 2.2V to 18V and an output voltage range of 2V to 18V, this converter provides significant flexibility for various power sources and applications.
The device operates at a fixed 1.2MHz PWM frequency, minimizing solution footprint. For light load conditions, it supports automatic Burst Mode operation, consuming only 50µA of quiescent current in sleep mode. System-level features include ideal diode or VIN priority modes, VIN and VOUT power good indicators, and accurate RUN comparators for independent UVLO thresholds. It also includes output disconnect in shutdown and a low shutdown current of 2µA.
Protection features include short-circuit protection, current limit, and thermal overload protection. The LTC3118EUFD#PBF is available in thermally enhanced 24-lead 4mm × 5mm QFN and 28-lead TSSOP packages, suitable for surface mount applications. Its ability to generate 5V at 2A for VIN > 6V and achieve up to 94% efficiency makes it ideal for systems with multiple input sources, backup power systems, and battery or super capacitor input applications.
