MP2225 Synchronous Buck Module

Chip introduction:
 
MP2225 is a high-efficiency synchronous rectification buck switching converter with built-in power MOSFET. It provides a very compact solution with excellent load and line regulation performance. The MP2225 uses a synchronous operating mode to achieve higher efficiency over the full load range. Current control mode provides fast transient response and makes the loop easier to stabilize. Comprehensive protection includes over-current protection and over-temperature protection.
The MP2225 is available in a space-saving 8-pin TSOT23 package, reducing the use of existing standard external components.
 
Wide input working voltage: 4.5V to 18V 
The output voltage can be adjusted as low as 0.6V.
The efficiency is as high as 97%.

The physical picture of the MP2225 module is as follows:
 
 
The module has three power input methods: DC socket and two There are three kinds of binding posts, onboard power switch and chip enable switch, and the voltage is output through the USB port and binding posts.
 
The output voltage of the MP2225 module is determined by the voltage dividing circuit of the chip's FB pin:
as shown in the schematic diagram below, the output is 3.3V.
 
 
The partial pressure formula is as follows:
