LTC1871 DC-DC High Power Adjustable Step-up Module 3.0~35V to 3.5~35V 100W with Digital Display Voltmeter

The LTC1871 DC-DC High Power Adjustable Step-up Module is an automatic booster module that provides stable power, making it suitable for use with unstable voltage sources or voltage conversion requirements.

  Features:  

• Incorporates advanced voltage meter microprocessor for display and LTC1871 controller for boosting, ensuring stability and efficiency.
• Utilizes power MOSFETs and current-detecting resistors to maximize efficiency up to 96.4%.
• Equipped with high power, low resistance MOSFETs, high current, high efficiency Schottky diodes, and thickened PCB wiring for reduced temperature rise and enhanced performance.
• Offers short circuit protection with a limit of 14A current.
• Features onboard voltmeter to display input/output voltage, selectable via button onboard.
• Allows voltage adjustment via onboard potentiometer and voltmeter.
• Provides special high-frequency, high-capacity, low-resistance aluminum electrolytic capacitors to reduce output ripple.
• Supports wide input voltage range from 3V to 35V and output voltage range from 3.5V to 35V.
• PCB size: 67mm x 43mm x 12mm.

  Special Instructions:  

• Start and connect the load before connecting a high-power load due to limited inrush current at startup.
• Additional capacitors are recommended for inductive loads.
• Ensure input voltage is above 4V for proper voltmeter operation.
• Output voltage should be higher than input voltage.
• Output power can exceed 75W, reaching up to 128W when input and output voltages are above 20V.
• When connected to a high-power load, switch on first before connecting the load to avoid current limiting self-locking protection.

  Package Includes:  

• 1 x LTC1871 DC-DC 3.5-30V 6A 100W Adjustable Step-Up Boost Converter Module
