LTC1871 100W DC DC Step Up Booster Converter Module Power Supply Voltage Regulator 3-35V to 3.5-35V with Voltmeter

Description:

1. The automatic booster module provides stable power. Suitable for unstable voltage source or voltage conversion.
2. This display part adopts an advanced voltage meter microprocessor, boosting part adopts LTC1871 controller, through the use of the power MOSFET on resistance and save the current detecting resistor, maximizing its efficiency to 96.4%.
3. Incorporate high power low resistance MOS pipe, large package, high current, high-efficiency Schottky, super-wide thickened wire of PCB low-temperature rise, high power, and high efficiency. Ultra-wide working voltage, when the input and output voltage is above 20V it can be up to 128W of output power.
4. Long-life type switching power supply special high-frequency high capacity and low resistance (low ESR) aluminum electrolytic capacitor to lower output ripple. Module chips used are imported materials, stable performance.
5. This module is a more intelligent, humane, high-performance module.

Tips:

1. When connecting a high-power load, it is recommended to start and connect the load because the inrush current at startup is very limited. Use additional capacitors for inductive load
2. The module has high power output and efficiency (up to 96%). The output can be up to 65W (and can further reach 100W when enhancing heat transfer).
3. Onboard voltmeter show input/output voltage (Select to show input/output voltage by pressing on the button onboard). When the "IN" LED lights on, the voltmeter displays input voltage; When the "OUT" LED lights on, the voltmeter displays the output voltage.
4. Adjust voltage by the potentiometer onboard and the voltmeter onboard.

Specification:

1. Input Voltage:3-35V(Note:When input voltage is less than 4V,onboard voltmeter will not work); Input Current:9A(Max)
2. Output Voltage: 3.5-35V DC(this board is boosting board,output voltage>=Input voltage); Output Current:6A(max)
3. Output Power:65W(when the input and output voltage greater than 20Vup to 100W); Conversion Efficiency:96%(the highest); Output Ripple: 40mV(TYP)
4. Onboard Voltmeter Range: 4-40V; Error:+/-0.1V; Press the button to switch the display between input or output voltage value.
5. Short circuit protection: yes (limit current 14A). (Note: When connected to a high-power load, you only need to switch the current very general effect to meet the current limit self-locking protection.
6. It is recommended to switch first and then access the load); Input reverses extreme protection: none (connect high-current diode of input series if necessary).
