MP1584EN-LF-Z 3A, 1.5MHz, 28V Buck Converter

Product Description

The MP1584 is a high frequency step-down switching regulator that integrates an internal high-side high-voltage power MOSFET. MP1584 adopts current control mode, which can provide 3A current output and fast loop response through simple compensation design. The wide input range of 4.5V to 28V makes it suitable for a variety of step-down applications, including those in the automotive environment. The 100µA operating quiescent current allows it to be used in battery powered applications. By reducing the switching frequency at light loads to reduce switching and gate drive losses, the MP1584 achieves high conversion efficiency over a wide load range. The frequency reduction function helps to prevent the inductor current from running out of control during the startup process, and the over-temperature protection ensures the stability and reliability of the operation. With a high frequency of 1.5MHz, the MP1584 can prevent EMI (Electromagnetic Interference) noise problems in some applications, such as possible interference problems in AM radio and ADSL applications. MP1584 adopts SOIC8E package with strong heat dissipation performance.
