Product Overview
The MP1584 is a 3A, high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution with a small external component footprint. Key Features: - Wide input voltage range: 4.5V to 28V - Adjustable output: 0.8V to 20V - Output current: up to 3A continuous - Switching frequency: 1.5 MHz (fixed) - Built-in synchronous rectification (no external Schottky diode needed) - Efficiency up to 92% - Soft-start, over-voltage, over-temperature, and short-circuit protection - Package: SOT-23-8 (very compact)
Procurement Notes
Use this page as a sourcing reference. Final availability, MOQ, lead time, and compliance assumptions should be confirmed through RFQ before ordering this part.
Substitute Selection Notes
When the original MPN is constrained, compare package, ratings, tolerance, temperature range, and compliance status before approving an alternate.
Typical Use Cases
Suitable for BOM review, maintenance sourcing, prototype replenishment, production-gap purchasing, and alternative-part screening.
