24V Micro Family DC-DC Converter Module Datasheet by VICOR

Category: Electronics, Other Semiconductors, Vicor Corporation

Overview

The 24V Micro Family DC-DC Converter Module from VICOR is a compact and efficient power conversion solution highlighted by its small footprint of 2.28 x 1.45 x 0.5 inches and advanced power processing technology. These modules are designed to operate with a DC input range of 18-36V and can provide DC outputs ranging from 3.3V to 48V. Applicable in various fields such as industrial and process control, medical, communications, defense, and aerospace, the converters offer up to 89% efficiency and a power density of up to 91W per cubic inch.

Key Features & Benefits

The module features include isolated output and up to 100°C operating temperature with full load. It withstands input surges up to 50V for 100ms, offers programmable output from 10 to 110%, and maintains regulation within ±0.4% from no load to full load. The product is also capable of operating at 75% power at 16V after startup. In terms of safety and durability, it demonstrates an isolation voltage capability, operating over a wide temperature range (-55°C to +100°C operating, -65°C to +125°C storage), and can be equipped with RoHS compliant pins. Parallel operation with N+M fault tolerance is supported for flexibility in complex applications.

Product Variations

Part numbers follow the VZ4C1ZTIOOBLZ scheme and can denote variations like efficiency, grade, power output, pin style, baseplate type, and output voltage. Efficiency levels are standard or enhanced, and grades indicate operational temperature ranges. Power output options are provided for different voltage levels (e.g., 3.3V at 75W up to 48V at 150W). Pin styles are varied including long Tin/Lead, ModuMate Gold, and RoHS-compatible options. The baseplate can be slotted or threaded for through-hole mounting.

Electrical Characteristics

Electrical parameters are specified over the full operating range, incorporating input voltage, output load, and baseplate temperature. Operational input voltage ranges from 18V to 36V, with undervoltage and overvoltage protection mechanisms built in. Output characteristics include a voltage set point within ±0.2% of nominal and temperature regulation as tight as ±0.002% per degree Celsius, ensuring stable performance under varying conditions. The converter is equipped to handle a programming range of up to 110% of nominal output voltage, appropriate for diverse application needs.

Thermal Specifications

Thermal resistance and capacity indicate the module’s ability to handle heat with different interface materials and airflow conditions, providing flexibility in thermal management strategies. In a typical setting using a flat, greased surface, the thermal resistance from the baseplate to a heat sink is between 0.24°C/Watt and 0.21°C/Watt.
