LTC7862EFE#PBF FEATURES

Normal OperationTransients and Faults and During StartupSurge Protection and High Output Currents

LTC7862EFE#PBF DESCRIPTION

The LTC®7862 high efficiency switching surge stopper pro-tects loads from high voltage transients. High efficiencyswitching allows high output currents, small solution sizes,and high reliability. During an input overvoltage event, theLTC7862 controls the gates of two external N-channelMOSFETs to act as a switching DC/DC step-down regu-lator. This maintains the output voltage at a safe value,allowing the loads to continue to operate through the inputovervoltage event. During normal operation, the LTC7862turns on the top external N-channel MOSFET continuously,passing the input voltage through to the output, with mini-mal voltage drop. Using a fast peak current comparator,the LTC7862 also limits the maximum output current toprotect against overcurrent and short-circuit faults.An adjustable timer limits the time that the LTC7862 canspend switching during an overvoltage, overcurrent, orstartup condition. When the timer expires, the externalMOSFETs are turned off for a cooldown period and thenthe LTC7862 restarts. By strictly limiting how long theLTC7862 can switch, when the power loss is relativelyhigh, the components and thermal design can be opti-mized for normal pass-through operation while still safelyoperating through high voltage input surges and/or over-current events.Overvoltage Protector RegulatesOutput at 28V During VIN Transient
