EV4570-F-01A Evaluation Kit 3A, 55V, Frequency-Programmable Step-Down Converter Evaluation Board
The EV4570-F-01A is an evaluation board for the MP4570/MPQ4570, a frequency-programmable, step-down switching converter with integrated internal high-side and low side power MOSFETs. It can provide 3A of continuous output current with peak current control mode for excellent transient response and efficiency performance.
The wide 4.5V to 55V input voltage range accommodates a variety of step-down applications, including industrial, PoE, and automotive applications, as well as printers with a DC high-voltage bus.
Valley current detection is used to avoid current runaway during over-current protection. It also has accurate and reliable over-voltage protection, and auto-recovery thermal protection. In addition, the optional external soft start is available. The enable and power good indication functions can be used to track power easily. In order to increase efficiency, the MP4570/MPQ4570 automatically scales down the switching frequency at light loads. Meanwhile, the low-side MOSFET turns off to reduce driver loss when zero inductor current is detected. Synchronous operation mode with the integrated low-side MOSFET helps reduce the conduction loss, external components, and saves space and cost.
The MP4570/MPQ4570 is available in a TSSOP-20EP package with an exposed pad.
