4A Buck Boost Converter Module Adjustable Buck Boost Board With LCD Display in Pakistan



Product description

LCD input and output voltage, output current output power;
Input anti-reverse protection, reverse connection will not burn;
Can be step-up and step-down, the output voltage 0.5-30V arbitrary regulation, limiting the current 0-4A arbitrary regulation;
Output anti-intrusion, the battery charge without additional anti-reflux diodes;
Button control output ON / OFF status, and you can set the power-on default is ON or OFF;
Ascending and descending chip used as the main controller, external 60V 75A MOS tube as a switch, double 60V 5A SS56 Schottky rectification, 60V voltage value, superior to the market immature XL6009 / LM2577 program (a lot Device pressure value is not enough, MOS tube and Schottky diode pressure value must be greater than the input plus input voltage value);
Output ripple small, LC filter;
With heat sink, send module support isolation column.

Input voltage: 5.5-30V (input voltage 5V, you can normally achieve buck-boost, but the voltage and current meter values ​​are not accurate; less than 4.7V, undervoltage protection)
Output voltage: 0.5-30V
Output current: long-term stable work in 3A, strengthen the heat can reach 4A
Output power: 35W natural cooling, heat dissipation to enhance 50W
Voltage display resolution: 0.05V
Current display resolution: 0.005A
Conversion efficiency: about 88%
Soft-start: Yes (very powerful with load startup, startup may fail)
Input reverse protection: Yes
Output anti-intrusion: Yes
Short circuit protection: yes
Working frequency: 180KHZ
Size: 6.6*4.8cm/2.6*1.89inch

Package Includes:
1 x Module
