MP1584 3A Step-Down DC-DC Converter IC

The MP1584 is a 3 A, high-frequency, non-synchronous step-down (buck) DC-DC converter with 4.5–28 V input and an integrated high-side MOSFET.

Product Overview

The MP1584 is a current-mode step-down regulator with an internal high-side MOSFET, providing 3 A output with fast loop response and easy compensation. The 100 kHz–1.5 MHz adjustable switching frequency avoids AM-band EMI, and the wide input range suits automotive and industrial environments.

Newfly supplies verified, RoHS-compliant MP1584-class converter ICs with cross-reference and BOM-matching support for production sourcing.

FAQ

Q: Is the MP1584 a synchronous or non-synchronous converter?

A: It is non-synchronous (uses an external catch diode). For synchronous alternatives, ask Newfly for a cross-reference.

Q: What is the input voltage range?

A: 4.5 V to 28 V, suitable for automotive and industrial rails.

Q: Can you provide a cross-reference?

A: Yes. Share your BOM and Newfly will suggest compatible step-down converter ICs.
