The LTC7841 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. The output voltage can be adjusted up to 60V with 0.2% resolution via a PMBus-compliant serial interface. The serial interface can also be used to read back fault status, input/output current, input/output voltage and temperature. System configuration and monitoring is supported by the LTpowerPlay® development system.
PolyPhase operation allows the LTC7841 to be configured for 2-, 3-, 4-, 6-, and 12-phase operation.
