60V Dual Output Step-Up Controller with Digital Power System Management

Description

The LTC7880 is a dual PolyPhase®DC/DC synchronous step-up switching regulator controller with I2C-based PMBus compliant serial interface. This controller employs a constant-frequency, current-mode architecture, with high voltage input and output capability along with programmable loop compensation. The LTC7880 is supported by the LTpowerPlay™ software development tool with graphical user interface (GUI).Switching frequency, output voltage, and device address can be programmed both by digital interface as well as external configuration resistors. Parameters can be set via the digital interface or stored in EEPROM. The gate drive for the LTC7880 can be programmed from 6.3V to 9V to maximize efficiency. Both outputs have an independent power good indicator andFAULTfunction.The LTC7880 can be configured for discontinuous (pulse-skipping) mode or continuous inductor current mode.ApplicationsAutomotive Always-On and Start-Stop SystemsIndustrial and Point of Load ApplicationsAll registered trademarks and trademarks are the property of their respective owners.
