Coiltronics、Coilcraft、TDK、Toko和Sumida。捕获二极管选择捕获二极管（方框图中的D1）仅在关闭时间内传导电流。正常运行时的平均正向电流可通过以下公式计算：I D（AVG）=I OUT VIN–VOUT VIN，其中IOUT是输出负载电流。大平均二极管电流发生在高压线输出短路时。对于这种坏情况，二极管电流将接近编程峰值电流的75%。二极管反向电压额定值应大于大工作输入电压。当OVLO引脚用于限制大工作输入电压时，二极管反向电压应大于OVLO引脚设置，但可能低于过压锁定期间的大输入电压。为了在满载时实现高效率，选择反向恢复时间短且正向压降低的捕获二极管非常重要。因此，肖特基二极管经常被用作捕获二极管。然而，肖特基二极管通常表现出比硅二极管高得多的泄漏。在睡眠中，捕获二极管泄漏电流将作为负载电流出现，并可能显著降低轻负载效率。低泄漏的二极管在给定电流下通常具有较大的正向电压降，因此需要权衡Coiltronics, Coilcraft, TDK, Toko, and Sumida. Catch Diode Selection The catch diode (D1 from Block Diagram) conducts current only during the switch off time. Average forward current in normal operation can be calculated from: I D(AVG) =I OUT VIN – VOUT VIN where IOUT is the output load current. The maximum average diode current occurs with a shorted output at the high line. For this worst-case condition, the diode current will approach 75% of the programmed peak current. The diode reverse voltage rating should be greater than the maximum operating input voltage. When the OVLO pin is used to limit the maximum operating input voltage, the diode reverse voltage should be greater than the OVLO pin setting, but may be lower than the maximum input voltage during overvoltage lockout. For high efficiency at full load, it is important to select a catch diode with a low reverse recovery time and low forward voltage drop. As a result, Schottky diodes are often used as catch diodes. However, Schottky diodes generally exhibit much higher leakage than silicon diodes. In sleep, the catch diode leakage current will appear as load current, and may significantly reduce light load efficiency. Diodes with low leakage often have larger forward voltage drops at a given current, so a trade-off
