XL0401 simulation ideal diode module uses a dedicated chip simulation ideal diode rectifier

The XL0401 Ideal Diode Module uses a dedicated chip simulation an ideal diode rectifier. The module uses a 5.5m low internal resistance MOS. The pressure drop at a large current is small.To largely reduce the fever, a 0.3V Schottky works at 10A, and the heating power consumption is 3W (in fact it will be much larger).The heat consumption is about 1W.

Working voltage: 3V -26V

Work current:

12V 25 ° C without cooling measures ≤10A (10A long -distance running test 30 minutes) 12V 25 ° C heat sink+ air -cooled ≤15A (15A long -distance running test 30 minutes) Theory is good for heat dissipation, but it is limited to the heat dissipation conditions above 15A or more.Unexposed long -distance test

Static current: 130UA (12V empty) Positioning method: welding fixation

Module size: 15 *12.8 *3.4mm (manual measurement)

Notice:

1. The module must be used together.

2. When working on a large current, you must pay attention to heat dissipation. Use long -distance running 10A to test (12V 25 ° C) during the heat dissipation measures, but because the module volume is small, it is still in a relatively hot state.

3. The module cannot replace the continuity diode in the switching power supply, but it can be used to output end anti -inverted irrigation.

4.3V The module internal resistance will be large when the small voltage is working, so the test value of the current when the current can be less than 12V can be used. For details, you can refer to the actual measurement parameters in Article 6.

5. The minimum voltage drop of the module is about 53mV, and it will not be 0 due to the low voltage pressure of the current.

6. Test voltage drop must be measured on the pad. The more detailed measurement of the use of the lines used, the larger the voltage drop will be reflected (online voltage drop). When the temperature rises, the pressure drop will fluctuate a certain value.Pay attention to heat dissipation, the above data is for reference, not necessarily each module is just the same, but the difference will not be too large

7. Since the module is not the real diode, in order to avoid the impact of the short -term peak pulse (if you may have it), you should add a large capacitor and match your voltage voltage diode on the output module.

8. You should avoid using the input terminal with a large voltage difference when the two plate outputs short connection (especially one plate 3.3V input, the other plate 26V input, the output should be specially avoided).

9. If there is a US -level or smaller voltage pulse in the voltage, the voltage at the module input end will increase slightly but not large. In actual testing, the 10US pulse input at 26V input will cause the input terminal voltage to pull the voltageEssence
