Overview
Generally, diodes are used for battery charging to prevent reverse power polarity protection, but the DC voltage drop is above 0.5V, even up to 1V, which brings a lot of heat and reduces the efficiency of the power supply. . This board uses a low RDS (on) MOSFET, and the voltage is reduced to 0.2V within the rated current range, which is beneficial to improve the power supply efficiency and improve the reliability and safety of battery charging. When the output of this board is connected to the normal battery polarity, the input is connected to the normal polarity, and the input is connected to the wrong polarity, it will not be charged.
Product Parameters
Input voltage: DC3-30V, the input voltage is within this range
Output voltage: the difference with the input voltage, maximum 0.2V
Output current: 4A, MAX, peak current maximum 6A
Dimensions: length 24mm, width 16mm
Note: The battery needs to be connected to the reverse connection protection board first, and the polarity cannot be wrong. When the output of this board is connected to the normal battery polarity, the input polarity is normal and the input is connected to the wrong polarity.
