Module Introduction
The XL0401 ideal diode module uses a dedicated chip to simulate the ideal diode rectifier. The module adopts a 5.5mQ low internal resistance MOS, which has a small voltage drop during high current operation, avoiding the high voltage drop of 0.7V of ordinary diodes. The reduction of voltage drop also greatly reduces heating. A 0.3V Schottky diode has a heating power consumption of 3W (actually much higher) when operating at 10A current. It has been tested that the XL0401 ideal diode operates at 10A current, with a voltage drop of about 100mV and a heating power consumption of about 1W.
Parameter Introduction
Working voltage: 3V-26V
Working current:
12V 25 ° C without heat dissipation measures ≤ 10A (10A long-distance test for 30 minutes)
12V 25 ° C heat sink+air cooling ≤ 15A (15A long-distance test for 30 minutes)
Theoretical heat dissipation can be done well with higher current, but with 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 (measured manually)
Precautions
1. The module must be used in common ground, and the positive and negative input terminals must not be reversed for protection.
2. When the module is working with high current, it is necessary to pay attention to heat dissipation. It has been tested with a long distance of 10A (12V 25 ° C) without heat dissipation measures, but due to the small size of the module, it is still in a relatively hot state.
3. Modules cannot replace freewheeling diodes in switch mode power supplies, but can be used for anti backflow at the output end.
4. When working at a low voltage of around 3V, the internal resistance of the module will be relatively high, so the current that can pass through will be less than the test value at 12V
