The LT3690EUFE#TRPBF is a versatile monolithic buck switching regulator designed for applications requiring high efficiency and robust performance. It accepts input voltages ranging from 3.9V up to 36V, with overvoltage lockout protecting circuits through 60V transients. This device integrates a 30mΩ N-channel synchronous switch, eliminating the need for an external Schottky diode and increasing efficiency. It supports a maximum output current of 4A.
The regulator utilizes current mode topology for fast transient response and good loop stability. It features adjustable frequency operation from 170kHz to 1.5MHz, allowing for optimization of component size and efficiency. The low ripple Burst Mode operation maintains high efficiency at low output currents, with quiescent current as low as 70µA at 12VIN to 3.3VOUT. The output voltage is adjustable from 0.8V to 20V, with a precise 0.8V feedback reference voltage.
Protection features include short-circuit robustness, frequency foldback, and thermal shutdown. A power good flag signals when the output voltage reaches 90% of the programmed level. The LT3690EUFE#TRPBF is supplied in a compact, thermally enhanced 4mm x 6mm QFN package with exposed pads for low thermal resistance, suitable for surface mount applications.
