The LTC3250ES6-2#TRPBF is a highly integrated, low noise charge pump DC/DC converter from Analog Devices, designed specifically for power-sensitive applications requiring a clean and stable 2V output. This device is engineered to deliver up to 50mA of output current while maintaining exceptionally low noise and ultra-low quiescent current, making it an ideal power solution for portable and battery-operated electronics where efficiency and longevity are paramount.

Housed in a compact 6-lead TSOT-23 package, the LTC3250 operates from an input voltage range of 2.7V to 5.5V, making it compatible with standard lithium-ion batteries, 3.3V system rails, and 5V supplies. Its unique low-noise architecture utilizes a constant frequency switching scheme to generate its regulated output voltage, minimizing the generation of conducted and radiated EMI that could interfere with sensitive adjacent circuitry, such as in RF modules, medical devices, and precision analog sensors.

A key highlight of this converter is its remarkably low quiescent current, which is typically just 12µA when unloaded. This feature is critical for extending battery life in always-on applications, as the IC consumes minimal power while in standby or lightly loaded states. The device achieves high efficiency across its entire load range by automatically switching between its 1:1 and 2:1 conversion modes based on the input voltage, ensuring optimal power delivery without the need for external inductors.

The LTC3250ES6-2#TRPBF also includes built-in protection features such as thermal shutdown and in-rush current limiting, enhancing the reliability of the end application. Its simple design requires only three small ceramic capacitors to form a complete DC/DC conversion solution, significantly saving valuable board space and reducing the total bill of materials cost.
