LTC781x's cascaded boost-buck solution delivers a fast transient response using continuous, non-pulsating input and output currents. The continuous, non-pulsating, input and output currents substantially reduce voltage ripple and EMI. LTC781x's low voltage ripple and reduced EMI make the controllers ideal for industrial, automotive, and high-power, battery-operated systems. The Analog Devices Inc. LTC781x Controllers operate from a 4.5V to 60V input supply and can maintain performance down to 2.2V after start-up. The controllers extend the operating run time in battery-powered systems with no-load quiescent current as low as 33µA.
