DC-DC up and down module input, wide voltage adaptation

• A step-up, step-down, buck-boost converter board, as stated in the description, maintains a pre-set voltage regardless of whether the voltage is above (step-down) or below (step-up) the pre-set value.
• It functions particularly well in situations when the power source is wildly fluctuating, such as solar panels.

Specifications:

• Input Range: 3.5V - 28V
• Output Range: 1.25V - 26V
• Input Current: 3A ( max ), no-load 18mA (5V input, 8V output, no-load is less than 18mA. Higher the voltage, the greater the load current. )
• Rated at 1A, 3A for short periods with heatsink
• Conversion efficiency: <94% ( the greater the pressure, the lower the efficiency )
• Switching frequency: 400KHz
• Output Ripple: 50mV ( the higher the voltage, the greater the current, the greater the ripple )
• Load Regulation: ± 0.5%
• Voltage Regulation: ± 0.5%
• Operating Temperature: -40 - +85
• Dimensions: 48mm * 25mm * 14mm ( L * W * H )
