The LT3481EMSE#TRPBF is a versatile and high-performance switching regulator from Analog Devices Inc. (ADI). It is a monolithic buck switching regulator that features an adjustable frequency range from 300kHz to 2.8MHz. This device accepts input voltages up to 34V (with a maximum of 36V), making it suitable for a wide range of applications.
The LT3481EMSE#TRPBF integrates a high-efficiency 0.18Ω switch, a boost Schottky diode, and the necessary oscillator, control, and logic circuitry onto a single chip. This integration results in a compact and cost-effective solution for power conversion.
The converter operates in current mode topology, which provides fast transient response and good loop stability. Additionally, it features a low ripple Burst Mode® operation that maintains high efficiency at low output currents while keeping the output ripple below 15mV in typical applications.
The LT3481EMSE#TRPBF further enhances efficiency at low output currents by sourcing bias current from the output when VOUT is above 3V. The RUN/SS pin allows for soft-start functionality by providing a controlled output voltage ramp with an external resistor and capacitor.
The device also includes features such as a power good flag that indicates when VOUT reaches 90% of its set output voltage, and a low shutdown current of IQ < 1μA. The LT3481EMSE#TRPBF is packaged in a small, thermally enhanced 10-pin MSOP and 3mm x 3mm DFN package with an exposed pad for low thermal resistance.
With its wide input voltage range, high maximum output current of 2A, adjustable switching frequency, and low ripple Burst Mode® operation, the LT3481EMSE#TRPBF is ideal for applications such as automotive battery regulation, portable product power supplies, distributed power supplies, industrial power supplies, and wall transformer regulation.
In summary, the LT3481EMSE#TRPBF is a highly efficient, compact, and versatile switching regulator that offers a range of features and benefits making it suitable for a wide range of power conversion applications.
