Adjustable DC-DC 100W Regulated Step-Up module with LED Voltmeter (6-7A, LTC1871, 3-35V, Step up) (booster)

High-power adjustable DC-DC step-up module (100W max) based on the LTC1871 controller. It features an integrated LED voltmeter to monitor input or output voltage via a dedicated button, with manual calibration capability and display off function.

Specifications

• Input voltage range: 3-35 VDC (voltmeter requires at least 4 V to operate)
• Output voltage range: 3.5-35 VDC (must be higher than input voltage)
• Maximum input current: 7 A
• Maximum output current: 6 A
• Output power: 75 W continuous, up to 100 W if both input and output voltages exceed 16 V
• Conversion efficiency: up to 96%
• Integrated voltmeter: range 4-40 V, accuracy ±0.1 V
• Short circuit protection: yes (current limit 14 A)
• Inductor: high-quality 12 A monoblock type
• Dimensions: 67 x 42 x 12 mm
• Weight: 38 g

Usage note: no input reverse polarity protection (add a diode if required). When connecting a high-power load, power on the module before connecting the load to avoid triggering current-limiting protection due to inrush current.
