Additional features include programmable soft start or tracking, accurate current limit, a power good output signal and FMEA (Failure Mode and Effects Analysis) verified for adjacent pin shorts and opens. Furthermore, the LTC3863 has a short-circuit recovery feature which guarantees a controlled output voltage ramp rate in soft-start after output voltage short circuit release. This feature assures clean transitions and limited inrush current under all operating conditions. The LTC3863 is available in 12-pin thermally enhanced MSOP and 3mm x 4mm QFN packages. The LTC3863E and LTC3863I versions operate from -40°C to 125°C junction temperature. The LTC3863H is guaranteed to operate from a -40°C to 150°C operating junction temperature. The LTC3863MP is guaranteed to operate from -55°C to 150°C operating junction temperature.
