1PC LM2596 DC-DC Booster Power Supply Module Output Adjustable Step-Up Module DC DC Step Up Converter Boost Board Features:1. LM2596 is a high-performance 400KHz 4A switch currency step-up (BOOST) module. This module LM2596 is coming with the 3rd generation high-frequency switch technology as the core chip, The performance is much higher than LM2577. 2. Wide input voltage: 3V~32V; Optimum operating voltage range: 5~32V; Wide output voltage: 5V~40V. 3. With 4A high efficiency MOSFET switches, so the efficiency can be up to 94%, (LM2577current is 3A only). 4. With ultra high switch frequency 400KHz , even if small capacity filtering capacitors can achieve very good results, ripple is smaller (Compare to LM2577 frequency 50KHz). Specification:Model: LM2596 boost module Module Properties: Non-isolated boost (BOOST) Rectification: Non-Synchronous Rectification Input Range: 3V ~ 32V Output Range: 5V ~ 35V Input Current: 4A (max), no-load 18mA (5V input, 8V output, no-load is le than 18mA. Higher the voltage, the greater the load current.) Conversion efficiency: Thank You For Your Trust Choice !
