The LTC®3890/-1 is a high voltage dual output synchronous step-down DC/DC controller that draws only 50µA when in standby mode with one output active and the output voltage in regulation. The 4V to 60V input supply range is designed to protect against high voltage transients, continue operation during automotive cold crank and cover a broad range of input sources and battery chemistries. Each output can be set from 0.8V to 24V at output currents up to 25A with efficiencies as high as 95%, making it well suited for 12V or 24V automotive, heavy equipment, industrial control, robotics and telecom applications.High Voltage Dual Step-Down Controller VIN 4V to 60V High Step-Down Ratios VOUT1 50A Quiescent 0.8V to 24V Current VIN ……
