LinearPi MkII ultra-low noise SMT linear power supply
LinearPi MkII ultra-low noise SMT linear power supply
Introduction
LinearPi MkII is a high quality audiophile grade manageable and expandable ultra low noise high current linear power supply. It could be the one of the greatest Linear power supply solution s for both digital and linear audio applications. Multiple LinearPi MkII s can be grouped into a whole power supply
system. LinearPi MkII can also be upgraded to ultra capacitor power supply by integrating with UcConditioner.
Specification s and Highlighted Features
- 0.8uV Ultra low noise level
- Ultra low output impedance
- High speed high current low noise soft recovery Schottky rectifiers with option al shunt capacitors
- Built in on/off control logic with on board or possible external on/off control switch
- Multiple LinearPi MkII s can be grouped as a whole power supply system by making use of the built in isolated master/slave control signal chain.
- Seamlessly integrates with UcConditioner to upgrade to an ultra capacitor power supply
- Continuous AC input mode for best possible sound quality
- Optional Kelvin sense input for better possible performance
- Deal with MLCC piezoelectric effect noise
- Double thickness 2oz PCB copper layer s for ultra lower ESR performance
- Heavy duty fully SMT design
LinearPi Pro new features
- 5A high current 3.3V/5V/12V high performance linear power supply
- Paralleling output stage for even lower output noise level
- Ultra-low output impedance for great dynamic response
- Much bigger heat sink to achieve to lower temperature at high current
- 29,000uF total filtering capacitance and high performance Schottky rectifiers
- Four layer PCB optimized for low noise performance
LinearPi Pro 5V will be great for RaspberryPi 5 or other high current low noise applications. Recommend transformers: 1182Q6 or 1182L6(parallel coils)
Please reference the LinearPiMkII user's manual before formal release.

External ON/OFF switch (optional)
Note: To use an external on/off switch, the on-board on/off switch must be kept at off position.
