LTC3895EFE#PBF Product Details
Linear Technology's LTC3895EFE#PBF is a high voltage non-isolated synchronous step-down switching regulator controller that drives an all N-channel MOSFET power stage. Its 4 V to 140 V (150 V abs maximum) input voltage range is designed to operate from a high input voltage source or from an input that has high voltage surges, eliminating the need for external surge suppression devices. The LTC3895EFE#PBF continues to operate at up to 100% duty cycle during input voltage dips down to 4 V, making it well suited for transportation, industrial control, robotic, and datacom applications.
