LT3582EUD#PBF is a DC-DC buck switching regulator IC from Linear Technology, Inc., and is part of their Constant Frequency Bias Regulator series. This device is specifically designed to optimize power efficiency, system size, and component cost.The LT3582EUD#PBF is a single-phase Synchronous Step-Down DC-DC Buck Switching Regulator that supports a wide input voltage range of between 4V and 75V, with an adjustable output voltage of 0.6V to 80V. The device features a switching frequency of up to 500kHz and utilizes a PWM control with local feedback for accurately regulating output voltages.The LT3582EUD#PBF is used in a wide range of applications, including automotive, industrial, computing, and telecom. The device provides superior efficiency across the entire input voltage range, and also includes a dynamic range of operation that allows it to efficiently power low current loads while maintaining high efficiency over the entire system.In addition, the LT3582EUD is an excellent choice for high-power applications such as LED lighting, motor control, and other power conversion applications. The device also features a programmable frequency range of 250kHz to 500kHz to accommodate low-noise, ultra-fast switching requirements.The working principle of the LT3582EUD#PBF is quite straightforward. The device consists of an input voltage, an output voltage, and a control circuit. The input voltage is supplied to the device through an input rectifier, and the output voltage is set by the internal voltage reference. The control circuit consists of a pulse width modulated (PWM) comparator and a master oscillator. The comparator monitors the output voltage with the internal reference voltage, and then generates a PWM signal that informs the master oscillator of the desired output voltage. The master oscillator then interprets the signal and drives the buck stage to achieve the desired output voltage. The external compensation network connected to the feedback loop gains together with the master oscillator forms a charge-pump circuit that powers the buck stage and controls the switching frequency of the device.Finally, the LT3582EUD#PBF also includes a power-good indicator that monitors the device’s output voltage, providing an accurate status of when the output voltage is in regulation or out of regulation.In conclusion, the LT3582EUD#PBF is an efficient, high power, single phase, Synchronous Step-Down DC-DC Buck Switching Regulator that supports a wide input voltage range and high switching frequency of up to 500kHz, making it an ideal choice for a variety of high-power and low-noise applications. The device also features a PWM control with local feedback for accurately regulating output voltages, and a power-good indicator for monitoring output voltage status.
