LTC7812EUH#PBF

DC DC Switching Controllers Overview

The LTC7812EUH#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 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 up to 38V and delivers output currents up to 8A in typical configurations.

DC DC Switching Controllers Feature Summary

• Integrates independent boost and buck controllers for flexible multi-output or cascaded regulation
• Supports pass-through operation where input voltage equals output voltage
• Drives all N-channel power MOSFET stages for efficient synchronous rectification

DC DC Switching Controllers Applications

• Wide input range cascaded boost plus buck regulators
• Low EMI pass-through boost plus buck regulators
• High efficiency DC/DC regulators with variable input voltages

DC DC Switching Controllers Procurement Notes
