LT3581EMSE#TRPBF is an efficiency boost regulator from Linear Technology. It is an adjustable high-efficiency synchronous step-up DC-DC converter with embedded high-side PMOS and low-side NMOS switches. This makes it ideal for applications where the input voltage is lower than the output voltage and a high level of efficiency is required.The LT3581EMSE#TRPBF is well suited for applications including telecom, networking, automotive, and industrial power supplies as well as battery operated devices. It has an adjustable switching frequency up to 2 MHz which makes it suitable for reducing EMI noise while maintaining high efficiency.The integrated PMOS and NMOS switches minimize output voltage ripple, allowing the output voltage to be closely regulated when connected to an LDO post regulator or an active load switch. The LT3581EMSE#TRPBF also features a programmable soft-start and frequency synchronization that allows the device to reduce input current inrush when the device is powered on.The LT3581EMSE#TRPBF offers a wide input voltage range from 3.2 V to 32 V and an output voltage range from 0.8 V to 30 V. This makes it suitable for applications where a wide range of input and output voltages are required. The maximum output current is 5 A, making it suitable for applications that require up to 1.2 W of power.The LT3581EMSE#TRPBF also features a patented adaptive on-time control scheme to regulate the output voltage. This scheme uses a current-mode control loop and an adaptive on-time control to effectively regulate the output voltage, while providing stable and fast transient response.The LT3581EMSE#TRPBF also features integrated protection and fault management circuitry. This circuitry ensures that the device will not be damaged in case of a short-circuit or over-current condition.Overall, the LT3581EMSE#TRPBF is an ideal solution for applications that require high efficiency and stable operation. Its wide input and output voltage capabilities, high output current, and integrated protection and fault management circuitry make it suitable for a wide range of applications.
