Description
PNMini2A is part of a kickstarter campaign.
 
The PNMini2A power module is a high efficiency converter (up to 92%) capable of Driving up to 2A load without using heat sink. The PNMini2A is available in an innovative small PCB that enhances thermal performance and allows for hand soldering or plugin use. It requires no external components. It is a reliable, robust and allows startup into a pre-­‐biased output. Other Significant features like better output accuracy (±1%) And lower standby current of 0.3mA Makes this module an ideal solution for many applications.

  • Industrial and car audio power supplies
  • DIY electronic projects
 
How do I use it?
 
Supply Rail Configuration
PNMini is extremely easy to use. There is no external component required. The three terminals of PNMini are input voltage VIN, output voltage VOUT, and ground connection GND. The VIN pin is always fixed as Pin 3. Depending on the system requirements, Pin 1 can be positive output VOUT(+) or GND; Pin 2 can be GND or negative output VOUT(-).
 
Input Range
The input range of the PNMini family is very wide to cover more DIY electronics applications. For PNMini-2A, the input range for positive output is 3.5V to 27V. The input range for negative output is 2.7V to 27V.
 
Output Programming
The output voltage is programmable through three feedback resistors connected from VOUT terminal to GND terminal.
 
 
Application Examples
PNMini can be used in all kinds of DIY electronics projects. Below are two application examples:
 
1. Arduino drone with longer battery life
PNMini can be used to power your Arduino drone. A miniature Arduino board is usually powered by 3.3V. The motors and sensors are usually 5V. You can use 3 li-ion battery stack and two PNMini to get the voltage you want! It's more efficient than LDO. PNMini provides up to 92% efficiency while LDOs can hardly achieve more than 50% efficiency. That's a 40% longer battery life for your design!
 
 
2. A simple ECG amplifier
Another application example is a simple ECG amplifier which can display your ECG waveform on a oscilloscope. For sensor or amplifier applications, dual supply is often preferred. Positive supplies are everywhere, but sometimes it's difficult to find a negative power supply. PNMini solves the problem by generating both positive and negative supply from a single source.
