Desription:
XL0401 ideal diode module adopts a special chip to simulate the ideal diode rectifier, and the module adopts 5.5mu03a9 MOS with low internal resistance, so the voltage drop is small when it works at high current, which avoids the high voltage drop of 0.7V of ordinary diode, and the reduction of voltage drop also reduces the heating to a great extent. When a 0.3V Schottky works at 10A current, the heating power consumption is 3W (actually it will be much larger). The measured XL0401 ideal diode works at 10A current, and the voltage drop is about 100mv, the heating power consumption is 1W
Parameter: Working voltage: 3V -26V Working current: 12V 25 ° C without heat dissipation measures u2264 10A (10A long-distance running test for 30 minutes) 12V 25 ° C heat sink+air cooling u2264 15A (15A long distance test for 30 minutes) Theoretical heat dissipation can be done well with higher current, but limited heat dissipation conditions above 15A Not tested for long-distance running Static current: 130ua (12V no-load) Positioning method: welding fixation Module size: 15*12.8*3.4mm (manually measured)
