LTC3112IDHD#PBF - High Efficiency, 15V, 2A Synchronous Step-Up DC/DC Converter
The LTC3112IDHD#PBF is a high-performance, synchronous step-up DC/DC converter designed by Linear Technology to meet the demands of a wide range of power supply applications. This versatile converter is capable of generating a 15V output from an input voltage range of 2.7V to 15V, making it ideal for single-cell Li-Ion, multi-cell alkaline, or NiMH applications as well as industrial, automotive, and portable electronics that require a higher voltage output.
With its 2A output current capability, the LTC3112IDHD#PBF is well-suited for applications requiring significant power in a compact footprint. Its high efficiency is achieved through the use of low-resistance N-channel MOSFET switches and a constant frequency, current mode architecture, which also provides excellent line and load regulation and low output ripple.
The device features an adjustable switching frequency, ranging from 300kHz to 2MHz, allowing designers to balance efficiency against external component size. By increasing the frequency, smaller inductors and capacitors can be used, which minimizes the overall solution footprint on the PCB. Moreover, the LTC3112IDHD#PBF includes a Burst Mode operation which is particularly useful in battery-powered applications as it reduces quiescent current to only 25µA, thereby extending battery life when the load is light.
Additional features of the LTC3112IDHD#PBF include a 1.2V feedback reference voltage, internal soft-start to limit inrush current during startup, thermal protection, and a power good flag that signals when the output is within 7.5% of its nominal value. The device is also capable of operating in a 100% duty cycle for low dropout performance, ensuring the output voltage is maintained even when the input voltage drops close to the output voltage.
Encased in a 16-lead DFN package, the LTC3112IDHD#PBF is designed to operate over a wide temperature range, from –40°C to 125°C. Its robust design and comprehensive feature set make it an excellent choice for engineers looking for a reliable and efficient power solution.
