LTC3835IGN-1#TRPBF belongs to the power management integrated circuits (PMIC) and more specifically, to the class of DC DC switching controllers, in the voltage regulators category. The integrated device is utilized to accurately and optimally manage the power in point-of-load (POL) applications, all within a single IC. Its high precision, fast response time and ability to deliver a wide range of output voltages makes it the perfect component for a diverse range of demanding applications like DSPs, FPGAs and ASICs.

The main task assigned to the LTC3835IGN-1#TRPBF component is supervising and dynamically controlling a POL power supply rail precisely as much as possible. This is achieved by using an inner voltage mode and a current mode control topology alongside with a feedback resistor, connected to the output regulator terminal. By constantly implementing the feedback voltage into the controller, the device can easily adjust the output voltage and maintain the steady voltage, regardless the changes in load current or temperature.

Aside from providing a highly accurate output voltage and working as a supervisor of the applied voltages on the POL, the LTC3835IGN-1#TRPBF can gain extra features and provide different functions. This is enabled by the use of external components like additional transistors, that can be added on the controller\'s pins. Similarly, through the use of external resistors and caps, the device is able to successfully program the step up, buck-boost and the inverting regulator modes.

Furthermore, the integrated circuit is able to support the majority of available input voltage sources ranging from 6V up to 60V. It also offers optimal integrators and reference designators as well as a configurable system undervoltage lockout (UVLO) and very low dropout output regulation. The device\'s current output is also configurable, allowing a maximal current limit of 40A or 85A, depending on the specific manufacture.

Finding its application in power supplies that require a precision level during the voltage regulation, the LTC3835IGN-1#TRPBF integrated IC is a highly capable device for the majority of point-of-loads systems. Its high precision, wide output range and external component support makes it the ideal component for powering FPGAs, ASICs, DSPs and other sensitive devices.
