LTC7841 Datasheet Polyphase Synchronous Boost Controller

Manufacturer: Analog Devices

Overview: LTC7841 PolyPhase Synchronous Boost Controller with PMBus Interface.

General Description

The LTC®7841 is a high performance PolyPhase® single output synchronous boost converter controller that drives two N-channel power MOSFET stages out-of-phase.

Multiphase operation reduces input and output capacitor requirements and allows the use of smaller inductors than the single-phase equivalent.

Synchronous rectification increases efficiency, reduces power loss and eases thermal requirements, enabling high power boost applications.

Key Features
