1pc LDO5A Mosfet Linear Pwer Supply (SingleRail)5-24VDC 5A  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:

use PMOS LDO architecture
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 rectifier bridge

The output voltage is continuously adjustable from 5-24V, no additional replacement of components is required.

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).

12VDC-OUT-5A

Input voltage VAC=(12+8)/1.414=14.14VAC, Please choose 15VAC;

Transformer Power= (15*5)*(1+0.3)=97.5W; Please choose 100W
