HiBCTR 5-Piece DC-DC Module
The HiBCTR module family provides a triple-output configuration with 3.3V, 5V, and 12V rails. It accepts 6V–12V input and delivers up to 800 mA total load across outputs. The design emphasizes a double-sided PCB layout to optimize traces and heat flow, which can improve performance in compact enclosures. This package supports a simple, compact approach for projects needing multiple rails from a single power source.
KEAcvise 5Pieces DC-DC Power Module
KEAcvise offers a 12V-to-3.3V/5V/12V triple-output module with a single 6–12V input range. It delivers 3.3V and 5V with tight regulation and up to 800 mA total current, while pass-through 12V keeps a direct path for that rail. The module uses a double-sided PCB, optimizing layout for stability, heat management, and EMI considerations. It’s suitable for embedded projects, automotive accessories, and compact lab benches needing multiple rails.
Kaito HY3003D-3 Triple Output
The Kaito HY3003D-3 combines two 30V, 3A linear outputs with a dedicated 5V, 3A output. It includes back-lit LED displays to monitor voltage and current and offers coarse and fine adjustment controls. Overload protection is provided to guard connected loads, delivering a lab-grade option for test setups requiring precise multi-rail outputs and straightforward benchmarking across rails.
MEAN WELL TKA30B-C
Mean Well’s TKA30B-C is a compact DC-DC converter in a 2″x2″ case with dual in-line package and robust isolation ratings (1000VDC option). It supports multiple outputs within a triple-output configuration, making it a staple for compact power modules in instrumentation, labs, and field installations. The device is designed for high reliability under demanding conditions, providing a balance of voltage rails with protective features typical of Mean Well’s industrial-grade products.
B&K Precision 1671A Triple Output
B&K Precision 1671A provides a triple-output digital display DC power supply suitable for bench and lab use. It emphasizes digital readouts for voltage and current across rails, with protections and overload safeguards. Its triple-output format makes it useful for testing circuits across different voltage domains in a single instrument, reducing the need for multiple separate supplies in a workspace.
Buying Guide: Key Considerations For Triple Output DC-DC Converters
- Voltage rails and regulation: Verify that the voltages you need (for example, 3.3V, 5V, and 12V) are all provided with tight regulation. Look for ±0.05V or better accuracy where you require precise reference levels.
- Input range and headroom: Ensure the input voltage range accommodates your source with enough headroom above the highest rail. A common input range is 6V–12V for triple-output modules.
- Current capacity per rail: Check current limits for each output and total load. Some modules share a total current budget; others provide independent rails. Plan your load distribution accordingly.
- Protection features: Over-current, over-temperature, short-circuit protection, and reverse polarity protection can extend reliability in automotive and rugged environments. Look for thermal design and shielding features if in tight enclosures.
- Efficiency and heat management: Higher efficiency reduces heat in compact boards. Consider thermal vias, heatsinking, and enclosure ventilation for continuous-running applications.
- Isolation and safety: Isolated designs provide galvanic separation between input and outputs, which can be crucial in mixed-signal or test environments. Check IS rating if relevant to your project.
- Form factor and mounting: Verify footprint fits your PCB or chassis. Some modules offer double-sided PCBs and compact dimensions suitable for tight spaces.
- Output monitoring: Digital displays or test points help validate outputs during development and troubleshooting. Some units offer fine-grain adjustment controls for calibration.
- Durability and environment: For automotive or outdoor use, consider seals, enclosure materials, and operating temperature ranges to ensure reliable operation in harsh conditions.
- Cost vs. value: Compare the combined features—voltage rails, protections, and physical size—against your budget to determine the best balance for your project timeline and reliability goals.
When selecting a triple-output DC-DC converter, align the product’s rail voltages, input range, and protection features with your system’s requirements. For lab benches, a unit with clear digital displays and robust safety features can simplify testing. For automotive or rugged environments, focus on protection, isolation, and thermal performance to ensure long-term reliability.
