20pcs DC-DC Buck Regulator Module 9V/12V/24V to 5V USB Charging Vehicle Power Supply Buck Charging Module

Description: Product size: 35.5*17*8.3mm Input voltage range: 6-26V The output voltage is 5.2V (considering the loss of charging line, the output terminal is about 5.2V, and the load terminal is about 5V). The maximum output current is 3A (without the heat sink, the output current is 2A). Note 1: Positive and negative can not be reversed, and the input voltage should not exceed 26V, otherwise it will cause chip damage. Note 2: When power on, you can't touch the sample resistance and IC foot on the circuit board by hand, otherwise it may lead to sudden change of output voltage and damage the equipment. Package Included: 20 x DC-DC Buck Regulator Module
