LTC7813MPUH#PBF

DC DC Switching Controllers Overview

The LTC7813MPUH#PBF is a high-performance synchronous Boost+Buck DC/DC switching regulator controller designed to drive all N-channel power MOSFET stages. It integrates independent step-up and step-down controllers capable of regulating two separate outputs or operating in a cascaded configuration. This topology allows the device to regulate an output voltage from an input voltage that is above, below, or equal to the desired output level. The component supports wide input ranges, typically spanning 4V to 56V or 8V to 60V depending on the specific application circuit, with adjustable output voltages ranging from 20V to 32V or lower values like 5V, 10V, 12V, and 24V. It delivers output currents up to 8A or 10A and operates within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Integrates independent boost and buck controllers for flexible dual-output or pass-through cascaded regulation

DC DC Switching Controllers Procurement Notes

Verify the exact suffix and package type against the manufacturer's current datasheet to ensure compatibility with your design requirements. Confirm the specific input and output voltage ranges supported by the intended application circuit, as these vary across different LTC7813 variants. Check for any automotive or industrial qualification certifications if required for your specific deployment environment.

DC DC Switching Controllers Selection Notes

Select this controller when the input voltage may fluctuate around the target output voltage, necessitating a pass-through topology. Consider the maximum input voltage limits and thermal performance for the expected load current. Ensure the external MOSFET selection matches the controller's drive capabilities and switching frequency specifications for optimal efficiency.
