LTC3260HMSE#PBF is a small, low-cost, high efficiency DC/DC switching regulator module, part of the DC/DC switching regulator family. It is commonly used in mobile gadgets and other electronic devices due to its ability to handle high current loads, lower the current ripple and reduce the switching noise. This PMIC Voltage Regulators DC DC Switching Regulators provides a regulated output voltage from an input voltage of up to 45 Volts. It also offers adjustable output voltages and current limits for various application. Additionally, it features an advanced safety features such as protection circuitry for input and output, thermal shutdown, and output under-voltage lockout.

The LTC3260HMSE#PBF has numerous applications ranging from power supplies for portable equipment, distribution of power for multiple devices and various other charging and energy production systems. It features a topology of synchronous buck and has a very wide range of output voltages from 0.5V to 18V, while its input voltage range spans from 4.5V to 45V. Further, it offers a high power density to efficiently power higher output voltages with low power dissipation. Additionally, the module is capable of accepting input voltages up to 45V, allowing it to handle higher voltage, which further increases the efficiency and performance of downstream devices.

The operability of the LTC3260HMSE#PBF relies upon two principal variables. Firstly, the input voltage, which supplies the power to the module and the output voltage, which is the voltage outputted by the module. By controlling the input voltage, input current and output voltage, the module can regulate the system. Another key variable is the power provided by the DC/DC output current. The output current determines the workload that the module can manage.

The working principle of the module involves controlling the input voltage level as per the output demand. The start-up current of the module is first fixed by the current limit and then flows through two channels; the high-side and low-side MOSFETs. Whenever the output voltage deviates from the set level and an output current is applied, the module tracks the input voltage, through a control loop, enabling the MOSFETs to switch between their on and off states. This ensures that the output voltage is maintained constant, at the desired level, by ensuring a constant input voltage.

On top of the exceptional efficiency, the module offers a comprehensive protection feature. The over-voltage protection (OV) prevents the connection of a dangerously high input voltage, which could potentially damage other circuitry, while the output over-voltage protection safeguards the load from receiving a higher than permissible voltage. It further features under-voltage protection and output over-current protection. Overall, the LTC3260HMSE#PBF is an efficient DC/DC switching regulator module that simplifies power supply, offer convenience and safety, while allowing the user to control numerous parameters of the module.
