LT1617ES5-1#TRPBF - Linear Technology Step-Up DC/DC Converter

The LT1617ES5-1#TRPBF is a compact, high-efficiency, step-up DC/DC converter from Linear Technology. Designed to operate as a boost converter, it is capable of increasing the voltage from a lower voltage input to a higher voltage output, essential for applications that require voltage levels not available from the power supply. This makes it an ideal choice for battery-powered devices where extending the battery life is crucial.

This particular model comes in a small SOT-23 package, which is highly valued for its space-saving footprint on printed circuit boards (PCBs). The LT1617ES5-1#TRPBF operates over a wide input voltage range from 1.2V to 15V, making it versatile for various applications, from single-cell Li-ion or multi-cell alkaline/NiMH batteries to other standard power supplies.

One of the remarkable features of the LT1617ES5-1#TRPBF is its fixed frequency operation at 1.2MHz, which allows the use of tiny, low-cost capacitors and inductors while providing a low noise operation. Additionally, it has a low quiescent current, which enhances its power efficiency, especially in battery-powered applications where every microamp of current saving is significant.

Protection features of the LT1617ES5-1#TRPBF include thermal shutdown and current limiting, ensuring the longevity and reliability of both the converter and the overall application. The device also offers a shutdown pin, which can be used to reduce the quiescent current to a mere 10µA during standby, further conserving battery life.

The LT1617ES5-1#TRPBF is suitable for a variety of applications, including but not limited to portable electronics, handheld instrumentation, small LCD displays, and bias voltages for GaAsFETs or other circuits requiring a high voltage supply. With its high switching frequency and the ability to produce a stable output voltage with high efficiency, this step-up converter is a practical solution for designers looking to enhance the performance of their power-sensitive devices.
