Overview
The VICOR Micro Family DC-DC converter module datasheet presents a detailed guide to a high-density, high-efficiency power conversion solution designed for a wide range of applications. These include industrial and process control, medical, Automated Test Equipment (ATE), communications, as well as defense and aerospace fields.
Key Specifications
With an input voltage range of 9V to 36V, the module offers isolated outputs and an input surge withstand capability of 50V for 100 milliseconds. The DC output range spans from 3.3V to 48V and allows for a programmable output between 10% and 110% of the rated output voltage. The module achieves up to 81% efficiency and features a power density of up to 60 watts per cubic inch.
Design and Features
Key product features include Zero-Current Switching (ZCS) and Zero-Voltage Switching (ZVS) architectures, which reduce noise and enhance efficiency. The unit is compact with a height above the printed circuit board of just 0.43 inches. Ensuring robustness in various conditions, the module operates at temperatures up to 100°C under full load, and its power derating applies when input voltage drops below 10V. Moreover, the modules are parallelable, facilitating N+M fault tolerance for reliable, flexible power systems.
Physical and Environmental Compliance
The module is compliant with RoHS standards when ordered with ‘F’ or ‘G’ pin options and features low-noise power conversion. Durability and longevity are hallmarks of this product, with an operating temperature range of -55°C to +100°C and a storage temperature range of -65°C to +125°C. Multiple pin styles and finishes are available, including options for RoHS-compliant gold pins and various baseplate configurations.
