Vicor V24B3V3H150BL | High-Density 150W Isolated DC-DC Converter

In modern power system design, the relentless demand for increased functionality within shrinking physical footprints presents a significant engineering challenge. The Vicor V24B3V3H150BL DC-DC converter directly addresses this challenge, delivering a potent combination of power, efficiency, and reliability in a compact, board-mountable package. It is engineered for applications where performance cannot be compromised by space constraints.

Product Highlights Overview

The V24B3V3H150BL is more than just a power converter; it's a foundational block for robust and efficient system architecture. Its design philosophy centers on maximizing usable power while minimizing thermal and electrical noise footprints.

Exceptional Power Density: Delivers a full 150W of regulated 3.3V power from a low-profile "Mini" size package, enabling significant board space savings.

Wide Input Range: Operates reliably from a nominal 24Vdc source, with a wide input range of 18V to 36V, making it ideal for battery-powered or fluctuating industrial bus applications.

High-Efficiency Operation: Leveraging advanced switching topologies, it achieves up to 88% efficiency, which critically reduces waste heat and simplifies thermal management.

Robust Isolation: Provides 3000Vrms of input-to-output isolation, ensuring safety and eliminating ground loop issues in complex systems.

Technical Deep Dive: The Core of Vicor's Performance

The standout performance of the Vicor V24B3V3H150BL is rooted in its use of a high-frequency Zero-Current Switching (ZCS) and Zero-Voltage Switching (ZVS) topology. Unlike conventional hard-switching Pulse Width Modulation (PWM) converters that incur significant Switching Loss, Vicor's architecture energizes the transformer sinusoidally. This approach allows power conversion to occur at extremely high frequencies with minimal losses because the switching elements transition when current or voltage is at zero.

The direct engineering benefit is twofold. First, the drastic reduction in waste heat is what makes the module's incredible power density possible. Less energy is wasted, meaning a smaller heatsink—or in some cases, no heatsink—is required. Second, this "soft-switching" technique generates significantly less high-frequency harmonic noise. This dramatically simplifies the system's EMI/EMC design, saving engineers valuable development time and reducing the need for bulky and expensive external filtering components.

Application Scenarios & Value Proposition

The unique features of the Vicor V24B3V3H150BL translate directly into tangible advantages across demanding industries:

Industrial Automation: In crowded control cabinets or integrated into robotic arms, its compact size and high efficiency are paramount. It delivers stable power for PLCs and sensors without adding significant thermal load to the enclosure, a critical consideration for system reliability.

ATE (Automated Test Equipment): The module's high power density allows test equipment manufacturers to build more channels into a single chassis, increasing throughput. Its low-noise characteristics ensure that the power supply does not interfere with sensitive measurements.

Telecommunications: In distributed power architectures for 4G/5G infrastructure, these modules provide efficient, isolated local power from a DC bus, ensuring uptime and signal integrity. The wide input range handles voltage sags and swells common in these environments.

Frequently Asked Engineering Questions

Our experts often address the following points during the design-in phase:

With such high power density, how should I approach thermal management?While the module's high efficiency minimizes heat, its compact form factor concentrates it. Effective thermal performance is achieved by mounting the module's flat baseplate directly to a suitable heatsink or a thermally conductive chassis. The module's low baseplate-to-heatsink thermal resistance is designed to facilitate efficient heat transfer. Proper thermal interface material and adequate airflow are key to maximizing reliability.

Can these modules be paralleled to achieve higher output power?Absolutely. The V24B3V3H150BL is designed for scalability. A dedicated pin allows for a simple, single-wire connection between multiple modules, enabling them to automatically share the load current accurately without the need for complex external balancing circuits. This makes it straightforward to design a power system that can scale from 150W to 300W or more.
