When using these modules remember that the output current will be a lot less than the input current, (remember - W = VA). For example, if you have a 10V output at 1A from a 5V input, the input current will be around 3.6A. The real-life maximum amount of power you can get out of these things is around 10W. 

Output current is greater than 2.5A (or output power greater than 10W) to work long hours, please add heat sink.

The MP1584 Step Down Module is based on MP1584 Switching Step Down Regulator from Monolithic Systems. The switching frequency of the module is very high, therefore small capacitors, with low ESR value can be used, which contributes to the small size of the module. Also, the life of the module increases as it does not include the bulky, low life cycle electrolytic capacitors. By switching at 1.5 Mhz high frequency, the module also prevents EMI noise problems, such as those found in AM Radio and ADSL Applications. Also the quiescent current of the module is very less, typically 125 µA. So, its applicable in low power devices.

The MP1584 Step Down Module is a variable voltage buck / step down regulator. It has a very sensitive variable resistor using which the output voltage can be set to required level.

• High Frequency Switching Step Down Voltage Regulator
• Up to 1.5 Mhz Switching Frequency
• Input Voltage Range: 4.5 V to 23 VDC
• Output Voltage Range: 0.8 V to 20 VDC
• Internal Current Limiting and Thermal Shutdown
