LTC7813MPUH#TRPBF

DC DC Switching Controllers Overview

The LTC7813MPUH#TRPBF is a high-performance synchronous Boost+Buck DC/DC switching regulator controller designed to drive all N-channel power MOSFET stages. It features independent step-up and step-down controllers that can regulate two separate outputs or be cascaded to manage an output voltage from an input voltage that is above, below, or equal to the output. The device supports wide input ranges, such as 4V to 56V or 8V to 60V depending on configuration, with adjustable output voltages typically between 20V and 32V or specific targets like 5V, 12V, or 24V. Output currents are configurable up to 8A.

DC DC Switching Controllers Feature Summary

• Supports cascaded operation to regulate output voltage regardless of whether the input is higher, lower, or equal to the output
• Contains independent boost and buck controllers for dual-output regulation or single cascaded topology
• Drives all N-channel power MOSFET stages for efficient synchronous rectification

DC DC Switching Controllers Applications

• Wide input range pass-through cascaded boost+buck regulators
• Low IQ cascaded boost+buck regulators with mid-rail inputs
• High efficiency DC/DC converters with multiple output rails

DC DC Switching Controllers Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the component matches the required thermal and electrical ratings for the target application. Cross-reference the part number with official Analog Devices documentation to avoid counterfeit risks and confirm availability status.

DC DC Switching Controllers Selection Notes

Select this controller when the design requires flexibility in handling input voltages that may vary significantly relative to the desired output levels. It is suitable for applications needing both step-up and step-down capabilities within a single stage or dual independent outputs. Consider the external MOSFET selection and passive component requirements based on the specific input and output voltage ranges defined by the system architecture.

DC DC Switching Controllers Part Context

This component belongs to the LTC7813 series of power management ICs from Analog Devices. It is categorized under non-isolated DC/DC switching controllers.
