POWER LOSS (W) LTC7841 PolyPhase Synchronous Boost Controller with PMBus Interface FEATURES DESCRIPTION n Wide V Range: 4.5V to 60V The LTC 7841 is a high performance PolyPhase single IN n 1% Total Output Voltage Accuracy Over output synchronous boost converter controller that drives Temperature at V = 12V two N-channel power MOSFET stages out-of-phase. IN n PMBus Compliant Serial Interface: Multiphase operation reduces input and output capaci- n Programmable V : tor requirements and allows the use of smaller inductors OUT Upto 60V with 0.2% Resolution than the single-phase equivalent. Synchronous rectifica- n Read Back of Average and Peak Temperature, tion increases efficiency, reduces power loss and eases Current, and Voltage (25Hz Refresh Rate) thermal requirements, enabling high power boost applica- n Fault Status tions. The output voltage can be adjusted up to 60V with n Phase-Lockable Frequency: 75kHz to 850kHz 0.2% resolution via a PMBus-compliant serial interface. n Less than 1ms Power-Up Time The serial interface can also be used to read back fault n Power Good Output Voltage Monitor status, input/output current, input/output voltage and n Internal LDO Powers Gate Driver from VBIAS or EXTV temperature. System configuration and monitoring is CC n Low Shutdown Current: I < 10A supported by the LTpowerPlay development system. Q n Clock Out for 4-Phase Operation (40A Output Current) PolyPhase operation allows the LTC7841 to be configured n Available in a Thermally-Enhanced 5mm x 6mm QFN for 2-, 3-, 4-, 6-, and 12-phase operation. n AEC-Q100 Qualification In Progress All registered trademarks and trademarks are the property of their respective owners.
