1pc LDO-10A Mosfet Linear Power Supply (SingleRail)5-24VDC MAX13A Kit DIY
DIY KIT Project：
DIY kit: Contains the PCB and the components needed on the PCB, but does not include the power transformer .
To complete this project, high level knowledge of electronics and rich experience in terms of soldering and testing are required.
Due to time zone and language communication restrictions, we can only provide limited technical support, and you need to solve problems by yourself.
Tech highlights：
Single-pass, series regulator design.
Low noise, high PSRR.
A constant-current source feeds a zener diode as a stable voltage reference.
A low-pass filter (with a corner frequency of 3.2Hz) prevents zener noise from being introduced into the error amplifier.
The low-pass filter also provides a soft-start characteristic.
Use a opamp as error amplifier to track output voltage stable as designed.
High-current MOSFET pass transistors.
The high current rating provides a very high safety headroom against overcurrent damage。
More sustained currents are possible by using larger, offboard heatsinks.
The negative temperature coefficient of MOSFETs prevents damaging thermal-runaway conditions that may plague conventional BJT devices.
Use Schottky Barrier Rectifier.
Total 4 Power MOSFETs for Voltage regulation.
The output voltage is continuously adjustable from 5-24V, no additional replacement of components is required.
support 10A continuous current, 13A maximum.
If you need other voltages, please contact us.
Do not short the output terminal to discharge capacitor, otherwise it will damage the power board.
Typical Application
Input voltage VAC= (Output voltage +8)/1.414
Please reserve 30% redundant power for the transformer
Transformer Power=VAC*I*(1+0.3)
For example:
12VDC-OUT-10A
Input voltage VAC=（12+8)/1.414=14.14VAC,
Please choose 15VAC；
Transformer Power= (15*10)*(1+0.3)=195W;
Please choose 200W
5VDC-OUT 9VAC-IN
9VD-COUT 12VAC-IN
12VDC-OUT 15VAC-IN
15VDC-OUT 18VAC-IN
18VDC-OUT 19VAC-IN
24VDC-OUT 22-24VAC-IN
