DC7V-35V to DC1.25V-30V LED Driver Charging Constant Current Voltage Step Down Buck Power Supply Module

Feature 1 This module uses the LM2596 chip high efficiency up to 92 low heat can be very easily used to above 3A current in conjunction with the original TI op amp control output current so the overall output is very stable 2 This module uses the original Sanyo low ESR filter capacitor you can make low ripple voltage to 50mV 3 This module uses machine placement reflow soldering 4 This module is an adjustable buck module the module can be adjusted from the blue adjustable resistor to change the output voltage Input and output differential pressure is 2V the minimum can be output 1 23V 5 Module indicated IN negative input IN positive input OUT negative output OUT positive output please note must be correct connected otherwise may cause damage to the module Description Nature of the module Non isolated step down moduleRectification Non synchronous rectificationInput voltage 7V 35VOutput voltage 1 25V 30VOutput current Adjustable 3A maximum Transfer efficiency 92 maximum Switching frequency 150KHzOutput ripple 50mV maximum 20M KbpsLoad regulation ±0 5 Voltage regulation ±2 5 Operating temperature 40°C to 85°CDimension 48 x 23 x 14mm L x W x H Battery charging method 1 Make sure the battery float voltage and charging current the module input voltage 2 Adjustment constant potentiometer the output voltage is adjusted to about 5V 3 Use the multimeter 10A current measuring the output short circuit current mea
