Nvarcher 3-ways DC Linear Stabilized Power Supply Fnished Board LT1963A /OP+MOS 12V 5V

Adopting the op amp plus field tube structure, the op amp adopts the new original Ti NE5534 op amp, and the field tube adopts the new original Infineon's IRF9Z34NS. The output voltage is stable and the ripple is low, and the response speed is fast, which is very suitable for supplying power to the DAC board. The board design takes into account that the user needs three independent power supplies, so it can be output as three separate sets of voltages.

 

AC input: 12V ~ 18V.

 

DC output voltage: plus or minus 12V, +5V. plus or minus 15V, +5V. plus or minus 18V, +5V

 

Output current: MAX 2A

 

Transformer requirements:

 

must be 4-wire output, that is, the secondary is independent winding, the tap type can not be used, otherwise the board and the transformer; the other transformer only two sets of winding output want to connect +5V must be connected from the input of the positive power supply Never input the lead from the negative power supply or burn the board and transformer;













There are 3 DC voltage stabilizing circuits, divided into LT1963A version and op amp + FET 2 versions, both of which are independent input and independent output.

Reminder: Because the two versions of power boards have different requirements for transformer windings, input voltage, and voltage levels. Improper use or wrong wiring may result in burnout of the transformer and power supply board.

 



 

LT1963A version introduction:
Using 3 completely independent LT1963 voltage regulator circuits, it can be set as 3 positive power supplies, or 1 positive power supply, 1 positive and negative dual power supply. The maximum output current of a single channel is 1.5A, the input can be DC and AC, and the output voltage range is 1.21V to 20V. LT1963 is a high-speed low-noise integrated voltage regulator chip, its index is much higher than ordinary voltage regulator devices such as LM317 LT317 ASM1117. It is commonly used on advanced DACs such as ES9018S to polish the power supply of the DAC to make the background details better.

PCB size: 10cm * 7cm

Input voltage: 3 AC6~15V, also can directly input DC6~20V
Output voltage: 1.2V-20V (adjustable), can be used as 3 positive power supplies, or 1 positive power supply, 1 positive and negative dual power supply.
Output current: 1.5A (max)

For this power supply board, when it needs to be set as a positive and negative power supply, the AC input terminal must be a 4-wire two independent windings, not a 3-wire center tap.



 





 

 

 

Operational amplifier OP+FET MOS version introduction


 Using high-speed op amp OP plus MOS field tube output architecture, the op amp adopts the new and original high-precision op amp OP07, the field tube adopts the new and original Infineon IRF9Z34 IRFZ34, etc., the output voltage is stable and the ripple is low, and the response speed is fast, which is very suitable Provide power to the DAC board.

PCB size: 10cm * 8cm

Input voltage: 3 AC AC6~18V

Output voltage: plus or minus 5~15V (adjustable), +5V~15V (adjustable)
Output current: MAX 3A
