XL4005 5A DC-DC adjustable step-down module

The XL4005 DC-DC Adjustable Step-Down (Buck) Converter Module is a high-performance power supply designed to convert higher DC voltages to lower, regulated levels. Supporting input voltages from 5V to 32V , it provides an adjustable output from 1.25V to 30V with a maximum output current of 5A , making it a versatile choice for many electronics and embedded applications. Built around the reliable XL4005 switching regulator IC , this module ensures high efficiency (up to 90%) and reduced heat generation compared to linear regulators. The onboard multi-turn potentiometer allows fine-tuning of output voltage. It features a large heat sink for improved thermal dissipation and screw terminals for easy wiring. Specifications: Input Voltage: 5V to 32V DC Output Voltage: 1.25V to 30V DC (adjustable) Output Current: Up to 5A (with heat sink; recommended < 4A for stability) Output Power: Up to 75W Conversion Efficiency: Up to 90% Switching Frequency: ~180 kHz Regulator IC: XL4005 Heat Sink: Pre-attached aluminum for better cooling Voltage Adjustment: Multi-turn potentiometer Connections: Screw terminals (IN+, IN-, OUT+, OUT-) Size: ~54mm x 23mm x 17mm Weight: ~28g
