Make a donation to ElecfarmThe MP1584 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It provides 3A output with current mode control for fast loop response and easy compensation.
The wide 4.5V to 28V input range accommodates a variety of step-down applications, including those in an automotive input environment. A 100µA operational quiescent current allows use in battery-powered applications.
Product includes professional library, confirmed schematic design. Our design has also a full output job and active Bill of Materials.
Features:
- Wide 4.5V to 28V Operating Input Range
- Fixed 3.3V @ 3A Output (Change output voltage by feedback resistor network)
- Programmable Switching Frequency from 100kHz to 1.5MHz
- Internal Soft-Start
- Ready to use in your devices
- Small size 25x15.5mm
