The LT3990EDD#TRPBF is an adjustable frequency monolithic buck switching regulator from LT, accepting input voltages from 4.2V to 62V. It features a low quiescent current of 2.5µA, making it suitable for power-sensitive applications. The integrated switch, catch diode, and boost diode simplify design.
This regulator operates with a wide switching frequency range from 200kHz to 2.2MHz, allowing for optimization between efficiency and component size. It supports output currents up to 350mA and offers fixed output voltages of 3.3V and 5V. Low ripple Burst Mode operation maintains high efficiency at low output currents, keeping output ripple below 5mVp-p in typical applications.
The LT3990EDD#TRPBF includes features such as accurate programmable undervoltage lockout, a power good flag, and internal current limiting for protection. It is available in a thermally enhanced 10-lead 3mm x 3mm DFN package, suitable for surface mounting.
This component is AEC-Q100 qualified, making it suitable for automotive battery regulation, industrial supplies, and power for portable products.
The input voltage range is 4.2V to 62V.
The quiescent current is 2.5µA at 12VIN to 3.3VOUT, and 2µA at 12VIN.
The maximum output current is 350mA.
The switching frequency can be adjusted from 200kHz to 2.2MHz.
Fixed output voltages of 3.3V and 5V are available.
The operating temperature range is -40°C to 125°C.
It is supplied in a 10-lead, 3mm x 3mm DFN package.
