MP4575GF
DESCRIPTION
The MP4575 is a frequency-programmable, step-down, switching converter with integrated, internal, high-side and low-side power MOSFETs. The MP4575 can provide 5A of continuous output current with peak current control for excellent transient response and efficiency performance.
The wide 4.5V to 55V input voltage range acmodates a variety of step-down applications, including industrial, Po E, automotive, and printers with a DC high-voltage bus.
The MP4575 uses peak-current-mode control to regulate the output voltage. The MP4575 provides over-current protection (OCP) with valley current detection, which is used to prevent the current from running away. The MP4575 also has accurate and reliable overvoltage protection (OVP) and auto-recovery thermal protection.
An optional external soft start is available. Enable and power good indication functions can be used to track the power easily. To increase efficiency, the MP4575 scales down the switching frequency automatically when the...
