ITEM NAME:DC 5.5-30V to 0.5-30V Digital LCD Display Step Up Down Buck Boost Module A#S Product Description Description: Feature: 1. LCD can display input and output voltage, output current and output power. 2. Anti-backconnection protection of input terminal, backconnection will not burn up. 3. Voltage can be boosted, voltage can be lowered, output voltage 0.5-30V arbitrary regulation, limiting current 0-4A arbitrary regulation. 4. The output terminal is anti-backfilling, and no anti-backfilling diode is added when charging the battery. 5. Keyboard control output ON/OFF status, and can set the default power on to ON or OFF. 6. Using step-up and step-down chip as main controller, external 60V 75A MOS transistor as switch, double 60V 5A SS56 Schottky as rectifier, 60V voltage withstand value is better than the immature scheme of XL6009/LM2577 on the market (many devices have insufficient voltage withstand value, the voltage withstand value of MOS transistor and Schottky diode must be greater than the input plus input voltage value). 7. Small output ripple, LC filter; typical value: about 100 mV. 8. Containing radiator, feeding module supports isolation column. Specification: Input Voltage: 5.5-30V (Input Voltage 5V, can also achieve step-up and step-down, but the measurement of voltage and current is inaccurate; under-voltage protection below 4.7V) Output voltage: 0.5-30V Output Current: It can work stably in 3A for a long time and reach 4A under enhanced heat dissipation. Output power: natural heat dissipation 35W, enhanced heat dissipation 50W Voltage display resolution: 0.01V Current Display Resolution: 0.002A Conversion efficiency: about 88%. Soft Start: Yes (high power module with load may fail when starting) Input Reverse Connection Protection: Yes Output anti-backfilling: Yes Short circuit protection: Yes Working frequency: 180KHZ Size: 66*48*21mm/2.59*1.88*0.82'' Installation hole: 4mm in diameter Weight: 46g Functional Description: 1. Module has IN/OUT and ON.Used as a general boost and buck module with over-current protection capability. Soft Start: Yes (high power module with load may fail when starting). Containing radiator, feeding module supports isolation column.
