300W 20A DC to DC Voltage Step-down Converter

SKU STEP-DOWN-CON Category

Only 2 left in stock

With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. The efficiency can be up to 96%, measured at 20A, converting 24V to 12V. It is designed with 75V/80A large current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, and gives a stable output. Wiring is convenient with these large current 30A screw terminals. The buck module has 2 heat sink that could enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and current.

Key features

Synchronous Rectification Logic: Utilizes dual independent 85V/80A high-current MOSFET structures instead of standard Schottky diodes. This layout limits internal voltage drops and drops generation of radiant waste heat. Independent CC / CV Management: Dual multi-turn trimming potentiometers give you analog command over output bounds. Turning them clockwise expands thresholds, while turning them counter-clockwise reduces boundaries. Six-Stage Low-ESR Capacitor Bank: Anchored by six dedicated high-frequency, low-resistance electrolytic filter caps. They effectively suppress incoming high-frequency line spikes and keep output power extremely smooth. Sendust Core Dual Inductor: Employs a dense, oversized Sendust magnetic loop wrapped in double-strand pure copper wire. This design maximizes magnetic flux efficiency while lowering core operating temperatures.
