LTC3260IMSE#TRPBF is a 3.3-to-2.5V, Programmable-Frequency, 600mA, Step-Down DC-DC Converter with Power Fail Input and Inductor DCR Sense. With a wide input voltage range of 2.7V to 5.5V and an adjustable operating frequency of 150 kHz to 2 MHz, it offers high efficiency, good output accuracy and fast transient response. The integrated power fail feature is independent of the regulator’s operating status so it will stay active even when the regulator is disabled. The LTC3260IMSE#TRPBF also features overcurrent limit, voltage sense, overvoltage protection and thermal shutdown to ensure that your system stays safe and stable.

The LTC3260IMSE#TRPBF is an excellent choice for any system that requires a reliable and efficient DC-DC converter. It is ideal for applications like point-of-load regulation, automotive and industrial supplies, and range from low voltage to intermediate voltage applications. The LTC3260IMSE#TRPBF can also be used to create a 12V output from a 3V input. The highly efficient operation of the LTC3260IMSE#TRPBF further ensures that your system will have low heat dissipation, leading to a cooler, more reliable operation.

The working principle of the LTC3260IMSE#TRPBF is based on a buck converter with an inductor providing energy storage during the switching cycle. The switching cycle is controlled by an internal PWM controller that can be programmed to adjust the frequency from 150kHz to 2MHz. The PWM controller also provides an overcurrent protection by monitoring the voltage at the inductor and providing the necessary steps to reduce the current. To reduce the power dissipation and increase efficiency, the device automatically enters a low power standby mode when the input voltage drops below the threshold.

In terms of footprint, the LTC3260IMSE#TRPBF is a very small form factor device, measuring only 2.8 x 2mm. This makes it suitable for space-constrained applications. The package is lead (Pb)-free, which means it complies with the environmental standards established by the US and European Union.

Overall, the LTC3260IMSE#TRPBF is a great choice for those looking for a high efficiency, programmable-frequency DC-DC converter with power fail input and inductor current sense. With its wide input voltage range and adjustable operating frequency range, it is suitable for a variety of voltage regulation applications, from low voltage to intermediate voltage applications. The small form factor and lead (Pb)-free package of the LTC3260IMSE#TRPBF also make it a great choice for space-constrained applications.
