Detail HW-140 Step Up Down 35W Buck Boost Converter LCD Display Module
Deskripsi HW-140 Step Up Down 35W Buck Boost Converter LCD Display ModuleFeature:
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
