Description
● Ultra-wide input voltage 3V ~ 32V ( the boost below 5V works normally, but the digital tube does not work) , the best working voltage range is 5 ~ 32V ; ● Super wide boost output voltage 5V ~ 40V ; ● Built-in 4A high-efficiency MOSFET switch tube, the efficiency is up to 94% ; ( LM2577 current is only 3A ) ● Ultra-high switching frequency 400KHz , you can achieve very good results with a small-capacity filter capacitor, the ripple is smaller and the volume is smaller (The frequency of LM2577 is only 50KHz ) ● With input display indicator and output display indicator, the IN indicator lights when the digital tube displays the input voltage, and the OUT indicator lights when the digital tube displays the output voltage Test comparison sample reference: Input 5V output 12V 0.8A 9.6W Input 7.4V output 12V 1.5A 18W Input 12V output 15V 2A 30W Input 12V output 16V 2A 32W Input 12V output 18V 1.6A 28.8W Input 12V output 19V 1.5A 28.5W Input 12V output 24V 1 A 24W Input 3V output 12V 0.4A 4.8W TECHNICAL PARAMETER : The nature of the module : non-isolated boost ( BOOST ) Rectification mode : non-synchronous rectification Input current : 4A (maximum), no load 18mA ( 5V input, 8V output, no load is less than 18mA . The higher the voltage, the greater the no load current.) Conversion efficiency : <94% (the greater the pressure difference, the lower the efficiency) Switching frequency : 400KHz Output ripple : 50mV (the higher the voltage, the greater the current and the greater the ripple) Load adjustment rate : ± 0.5% Voltage regulation rate : ± 0.5% Working temperature : -40 ℃ ~ +85 ℃ Dimensions : 65mm * 39mm * 14mm (length * width * height)
