United Arab Emirates the switching frequency of the AC-DC switching power supply module?(1)
What is the operating frequency of United Arab Emirates the AC-DC switching Marine boost/buck voltage power supply module? What factors need to be considered when choosing an AC-DC switching Marine boost/buck voltage power supply module? Are these questions the focus of your circuit design? The following are several elements for selecting the operating frequency.
Remote control switch circuit
The remote control switch operation of the module power supply is carried out through the REM terminal. There are two general control methods:
(1) REM is connected to -VIN (reference ground), the remote control is turned off, and VREF<0.4V is required. REM is suspended or connected to +VIN, the module works, and VREM>1V is required.
(2) REM is connected to VIN, the remote control is turned off, and VREM<0.4V is required. REM is connected to +VIN, the module works, VREM>1V is required. REM is suspended, and the remote control is turned off, that is, the so-called "suspended shutdown" (-R).
If the control is to be isolated from the input, an optocoupler can be used to pass the control signal
United Arab Emirates Choosing the switching frequency of the Marine boost/buck voltage power supply does not mean choosing the switching frequency of the Marine boost/buck voltage power supply with a good switching frequency, but the choice is suitable for your own use. Most of the current market is like this. The frequency of the AC-DC switching Marine boost/buck voltage power supply module is between 50K and 135K, and this frequency range can meet most applications. Let's discuss it. Some of the problems that AC-DC encounters when choosing switching frequency:
