The LT3990EDD#TRPBF is a monolithic buck switching regulator designed for efficiency and low power consumption. It accepts a wide input voltage range from 4.2V to 62V and delivers up to 350mA of output current. The device operates with a low quiescent current of 2.5µA, making it suitable for battery-powered applications.
Key electrical specifications include an adjustable switching frequency from 200kHz to 2.2MHz, integrated boost and catch diodes, and a low shutdown current of 0.7µA. It also features a power good flag and an accurate programmable undervoltage lockout.
This regulator is available in a small, thermally enhanced 10-pin DFN package, suitable for surface mounting. Its AEC-Q100 qualification makes it ideal for automotive battery regulation and other demanding industrial applications.
The LT3990 series offers fixed output voltages of 3.3V and 5V, alongside an adjustable output option. The current mode topology ensures fast transient response and good loop stability.
