● Ultra-wide input voltage 3V~32V, the optimal working voltage range is 5~32V;

● Ultra-wide output voltage 5V~45V;

● Built-in 4A high efficiency MOSFET switch tube for up to 94% efficiency; (LM2577 current is only 3A)

● The ultra-high switching frequency is 400KHz, which can achieve very good results with a small-capacity filter capacitor. The ripple is smaller and the volume is smaller. (LM2577 frequency is only 50KHz)

 

Output voltage range: DC 4V to 45V continuously adjustable, high efficiency (maximum 96%) maximum output current is 4A.

Advantages: Double-sided thick high-quality PCB boards are used, all of which use imported SMD aluminum electrolytic capacitors and high-Q high-power inductors. In addition, each board has undergone rigorous technical testing, and all tests have been completed using a separate antistatic protective bag.

 

Dimensions: 43mm * 21mm * 14mm (length * width * height) (including potentiometer) components and materials are the smallest! It is more convenient for customers to install various outer casings and better fixing.

 

IN+ input positive IN- input negative!
OUT+ output positive OUT-output negative

Precautions:  
※This module has higher conversion efficiency than the LM2577’s triode push mode.

※This module is an adjustable boost module, which can adjust the precision multi-turn adjustable potentiometer on the module.
To change the output voltage. The maximum output voltage is 45V. Turn the clock down in time, and turn the boost in reverse.

※ GND (input negative), IN+ (input positive), GND (output negative), OUT+ (output positive) indicated on the module.

※Working temperature:: Industrial grade (-45 °C ~ +85 °C) (Environmental temperature exceeds 40 degrees, please reduce power usage, or strengthen heat dissipation)
