V48C3V3C50BL
Vicor V48C3V3C50BL Micro brick DC-DC converter, 48 V input (36 to 75 V), isolated 3.3 V output at 50 W in the quarter-brick package.
The V48C3V3C50BL is a Vicor Micro brick DC-DC converter from the Maxi, Mini, Micro family that established the industry-standard brick footprint. It accepts a nominal 48 V input with a 36 to 75 V operating range and delivers an isolated, regulated 3.3 V output at up to 50 W, in the quarter-brick package measuring about 57.9 by 36.8 by 12.7 mm. The family uses low-noise zero-current and zero-voltage switching (ZCS/ZVS), so it delivers high power density with low noise and high efficiency, and it provides the features expected of a mature power component: single-wire paralleling for N+M fault tolerance, output voltage adjust, logic enable and disable, input undervoltage lockout and output overvoltage protection. The standard footprint, pin styles and baseplate options make the family easy to design in and second-source, and a comprehensive applications manual supports detailed design. Typical uses include telecom and networking power, industrial control, computing and distributed power architecture where a low-voltage logic rail is needed from a 48 V bus. Every module BeiLuo ships is factory-traceable and supplied with an import declaration, a certificate of origin and a RoHS compliance file, together with FAE support for thermal, filtering and paralleling design.
FAE Professional Review
The V48C3V3C50BL is a practical way to derive a quiet 3.3 V rail from a 48 V bus when the load is moderate. It shares the family footprint, so it slots into an existing brick layout. Because a 3.3 V output runs at higher current, pay attention to the output trace resistance and the baseplate cooling.

Frequently Asked Questions
What projects suit the V48C3V3C50BL?
It suits designs that run from a 48 V bus and need an isolated, low-noise 3.3 V logic rail at up to 50 W, such as telecom, industrial and instrument equipment. It shares the family footprint with the higher-voltage members.
Mind the output trace resistance at 3.3 V.
How do I handle the higher output current?
At 3.3 V the output current is higher for the same power, so size the output copper generously and keep the sense connections Kelvin at the load for good regulation. The baseplate carries the heat, so ensure a good thermal path.
Our FAE team can review your layout.
