The Power by Linear  LTC7810 is a high voltage non-isolated dual output synchronous step-down DC/DC controller that drives all N-channel MOSFET power stages. Its 4.5V to 140V (150V abs max) input voltage range is designed to operate from a high input voltage or from an input that has high voltage surges, eliminating the need for ...
