DC-DC Buck Converter

Product ID: 1207 This is an LM2596 DC-DC buck converter step-down power module with high-precision potentiometer for adjusting output voltage, capable of driving a load up to 3A with high efficiency. When the output current required is greater than 2.5A(10W) an external heat-sink is suggested. Input: DC 3V to 40V (input voltage must be higher than the output voltage to 1.5v above cannot boost) Output: DC 1.5V to 35V voltage continuously adjustable, high-efficiency maximum output current of 3A. Module Properties: non-isolated constant voltage module Rectification: non-synchronous rectification Input voltage: 4.5V-35V Output Voltage(Less than input): 1.3V-30V Output current: 3A maximum Conversion efficiency: 92% (maximum) Switching frequency: 150 KHz Output ripple: 50mV (maximum) 20M-bandwidth Load regulation: ± 0.5% Voltage regulation: ± 2.5% Operating temperature: -40 ℃ to +85 ℃
