ماژول رگولاتور کاهنده 0.8V- 18V/3A DC-DC MP1584

مشخصات

این ماژول رگولاتور ولتاژ بر پایه تراشه MP1584 کار می کند که ولتاژ ورودی 4.5V تا 28V را به ولتاژ 0.8V - 18V با جریان خروجی 3A تبدیل می کند.

• Input Voltage: 4.5V-28VDC
• Output Voltage: 0.8V-18VDC
• Continuous Output Current: Max. 3A
• Perk Output Current: 4A
• Max. Efficiency: 92%
• Output Ripple: ＜30mV
• Switching Frequency: 100kHz to 1.5MHz
• Operating Temperature: -40℃ to +85℃
• Dimensions: 22mm*17mm*4mm(l*w*h)

• Wide 4.5V to 28V Operating Input Range 
• Up to 92% Efficiency 
• Programmable Switching Frequency from 100kHz to 1.5MHz 
• High-Efficiency Pulse Skipping Mode for Ceramic Capacitor Stable 
• Internally Set Current Limit without a Current Sensing Resistor 
• Cycle-by-Cycle Over Current Protection 
• Input Under Voltage Lockout

Note: Input must be >1.5V higher than output! The chip will jumper to high temperature protection mode when it work at a high-power conversion, without any cooling, it is able to output 3A current at 5V. But at higher output voltage, the current output capacity is lower than 3A, the minimum is 2A.
