Description

The LTC7810 is a high performance dual step-down DC/DC switching regulator controller that drives all N-channel synchronous power MOSFET stages that can operate from voltages up to 140V. A constant frequency current mode architecture allows a phase-lockable frequency of up to 720kHz.The low no-load quiescent current extends operating run time in battery-powered systems. The LTC7810 features a precision 1V reference, enabling the output voltage to be programmed from 1V to 60V. The gate drive voltage for the LTC7810 can be programmed to 6V, 8V, or 10V to allow the use of logic-level or standard-threshold FETs and to maximize efficiency.The LTC7810 additionally features spread spectrum operation which significantly reduces the peak radiated and conducted noise on both the input and output supplies, making it easier to comply with electromagnetic interference (EMI) standards.APPLICATIONSAutomotive and TransportationIndustrial and TelecommunicationsMilitary/Avionics
