CI de potencia regulador conmutado DC/DC Texas Instruments LM2594HVN-ADJ/NOPB PDIP-8 tensión de salida ajustable…

The LM2594HVN-ADJ/NOPB is an adjustable DC/DC switching regulator IC in a PDIP‑8 package designed for step‑down (buck) voltage conversion. It integrates an on‑chip switch and control circuitry to provide a regulated output adjustable via external components. The device is suited to board‑level power supply designs, voltage regulation in embedded systems, prototyping and repair or replacement of compatible regulator modules where an adjustable output and simple implementation are required.

Advantages

The regulator offers efficient step‑down conversion with an integrated power switch, reducing external component count and board space compared with discrete solutions. Its adjustable output lets designers set the required voltage using standard resistor networks. The PDIP‑8 package simplifies handling and prototyping on through‑hole boards and breadboards. Thermal and electrical characteristics are suitable for a range of embedded and industrial applications when used within specified limits.

Suitable for

• Board‑level power supplies for embedded systems
• Prototyping and development on breadboards and through‑hole PCBs
• Replacement of compatible adjustable regulator modules
• Voltage regulation for sensors, microcontrollers and peripheral circuits

Key specifications

• Function: Step‑down (buck) switching regulator with adjustable output
• Package type: 8‑lead PDIP (through‑hole)
• Integrated on‑chip switch and control circuitry for power conversion
• Adjustable output voltage via external feedback resistor network
• Suitable for board‑level implementation and prototyping

How to use

Configure the output voltage by connecting the recommended external resistor divider between the output, feedback and ground pins according to the device's application guidelines. Use the specified inductor, diode and input/output capacitors chosen for current rating and switching frequency to ensure stable regulation and low ripple. Mount the PDIP‑8 package on the PCB or breadboard with adequate spacing for heat dissipation. Verify input voltage range and thermal limits before applying load, and follow standard layout practices for switching regulators to minimize noise and ensure stable operation.
