Product Description

Engineered for demanding high-voltage environments, the LM2596HVS DC-DC Buck Converter is a rugged step-down power module capable of handling input voltages up to 50V. Unlike standard LM2596 modules limited to 35-40V, the "HVS" (High Voltage Series) version utilizes a high-performance voltage regulator IC to safely step down power from high-voltage sources like 48V battery banks, industrial power supplies, or large solar arrays. At Robogears, we recommend this module for its high-frequency 150 kHz switching, which allows for smaller filter components and exceptionally low output ripple. With its multi-turn potentiometer, you can precisely tune the output voltage to power anything from 5V microcontrollers to 24V industrial relays from a high-voltage input.

Detailed Key Features

  • High-Voltage Input Range: Specifically designed to handle up to 50V DC input, making it ideal for 36V and 48V battery systems where standard buck converters fail.

  • Precision Voltage Tuning: Features a 25-turn multi-turn potentiometer for ultra-fine adjustment of the output voltage to within millivolts of your target.

  • High Efficiency Step-Down: Operates with an efficiency of up to 92%, minimizing heat dissipation even when performing large voltage drops.

  • Compact Power Solution: Despite its high voltage rating, the module maintains a small footprint, suitable for embedding into control panels or portable device housings.

  • Stable Power Delivery: Low ripple performance ensures that sensitive electronic sensors and communication modules receive clean, stable DC power.

All Technical Details

  • Potentiometer: Multi-turn precision trimmer (Clockwise to increase, Counter-clockwise to decrease).

  • Thermal Performance: Integrated thermal shutdown protection and current limiting for safe operation.

  • Load Regulation: ± 0.5% stability under varying load conditions.

  • Voltage Regulation: ± 2.5% accuracy.

  • Interface: Clearly marked IN+/IN- and OUT+/OUT- solder pads for reliable connectivity.

Prototyping & Engineering Tips (Robogears Exclusive)

  • The High-Voltage Safety Rule: When working with inputs above 36V at your Pimpri facility, ensure all input connections are securely soldered and insulated. Accidental shorts at high voltages can cause significant damage to the module and neighboring components.

  • Heat Management: While the module is rated for 3A peak, we strongly recommend a maximum continuous current of 2A for long-term reliability. If your application requires more than 15W of power conversion, consider adding a small aluminum heatsink to the LM2596HVS IC.

  • Differential Requirement: For stable regulation, always maintain at least a 2V difference between the input and output voltages (e.g., to get a stable 12V output, your input should be at least 14V).

  • Capacitor Discharge: When testing high-voltage inputs, remember that the onboard capacitors may hold a charge for several seconds after power is disconnected. Always use a multimeter to verify the board is discharged before handling.
