Description
Product Overview
The 200W 15A DC-DC Buck Converter Module is a high-performance, adjustable step-down (buck) voltage regulator engineered for demanding power conversion applications. Based on synchronous rectification technology, this module efficiently converts a higher DC input voltage (8V-60V) into a lower, user-adjustable output voltage (1V-36V) with a continuous current capacity of up to 15A .
Synchronous buck converters replace the traditional catch diode with a low-resistance MOSFET, dramatically improving conversion efficiency (up to 94%) and reducing heat generation compared to asynchronous designs . This makes the module ideal for high-power applications where thermal management is critical.
The module features a robust aluminum housing that serves as an effective heatsink, allowing for natural cooling up to 100W and forced-air cooling up to 200W . An onboard multi-turn potentiometer enables stepless output voltage adjustment, while comprehensive protection circuits safeguard against overcurrent and reverse polarity .
Key Features
-
High-Power Output: Delivers up to 200W of output power (with enhanced cooling) and 15A peak output current, suitable for powering high-demand loads .
-
Wide Input & Output Ranges: Accepts DC input from 8V to 60V and provides continuously adjustable output from 1V to 36V (default factory setting 12V) .
-
Synchronous Rectification Technology: Uses synchronous MOSFET switching instead of a Schottky diode, achieving up to 94% conversion efficiency and significantly reducing heat generation .
-
Compact Aluminum Housing: The module is encased in a durable aluminum shell (70x38x31mm) that acts as a built-in heatsink for effective thermal management .
-
Dual Cooling Capacity: Under natural convection (passive cooling), the module supports 100W continuous output. With added forced-air cooling, it can sustain up to 200W .
-
Adjustable Output via Potentiometer: An onboard multi-turn potentiometer allows for stepless output voltage adjustment from 1V to 36V, with a default factory setting of 12V .
-
Built-in Protection Features: Includes overcurrent protection (OCP) and reverse polarity protection to prevent damage during fault conditions .
-
Non-isolated Step-Down Topology: The module is a non-isolated BUCK converter, meaning the input and output share a common ground, which simplifies integration but requires proper grounding practices .
-
High-Current Screw Terminals: Features solderless, high-current screw terminals for secure, tool-free wiring of input (IN+, IN-) and output (OUT+, OUT-) connections .
