The catch diode
網頁External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the LM2594 is used as shown in the Figure 16 test circuit, system performance will be as shown in system parameters section . 網頁2024年2月25日 · D1 is not best described as a 'catch' diode. That's a better description of the diode across a relay coil, which 'catches' the high voltage transient when its driver turns off. In a buck converter, best to call it a 'freewheel' diode. During the on phase of the IC, the output is taken up to the input voltage.
The catch diode
Did you know?
網頁One of the common uses of Schottky diodes is as an alternative to a fast rectifier diode in an SMPS circuit. All the arguments previously raised for a fast rectifier apply (i.e. fast reaction to both forward current and reverse transient, spike protection) with the additional benefit in SMPS circuits of a low forward voltage drop, hence low loss. 網頁The maximum operating temperature of the diode is 125C while the maximum temperature of the IC Is 150C. For the schematic, my recommendations are: 1. R18 is recommended to be between 240Ohm and 1.5kOhm. Then calculate R19 accordingly. This is to minimize the nose of the sensitive feedback pin.

網頁1. External components such as the catch diode, inductor, input and output capacitors can affect the switching regulator system performance. When the LM2574 is used as shown in the Figure 16 test circuit, the system performance will be as shown in the 2. 網頁The diode is a device that allows current to flow in one direction, but not the other. Its most basic use is, therefore, to rectify AC into DC. The arrow-head on the diode denotes the …
