We all have heard a lot about buck and boost circuits and know that basically these circuits are used in SMPS designs for stepping up or stepping down a given voltage at the input. The interesting thing about this technology is that it allows the above functions with negligible heat generation...
the amplification stage is a high speed switching circuit and what defines this design as Class D. A Class D amp could, in fact, use a conventional power supply; and a linear amp could use a SMPS. A traditional power
The first circuit will convert a 220V AC input to any desired output level from 100V to 220V, however the output will be a DC, so this circuit may be used for operating a foreign equipment which might be employing an AC/DC SMPS input power supply stage. The converter will not work wit...
Power supply rejection ratio LDOs, being linear circuits, produce much less noise than switched-mode power supplies (SMPS) or power converters. In many applications, an LDO is used locally on the circuit board, but the power source is an SMPS. Due to the control system w...
Closely related to SMPs are shape-changing polymers (SCPs), which change shape more gradually when they're heated (or energetically stimulated in some other way) and return to shape when cooled. Although self-healing materials (ones that repair themselves after damage) can work in various ...
Assume that the highest noise component will typically be at the switching frequency of the switch-mode power supply (SMPS). The power circuit using the TPS54360 has a switching frequency of 918kHz. You can estimate the noise or obtain the baseline noise figure at the switching frequency ...
The GUI works strictly with a communication interface board and allows real-time monitoring of the device as well as NVM and EEPROM content checking and programming. For more information about the GUI and the interface board, please refer to the UM2342 - user manual: Getting st...
If it is a desktop, make sure that the power cable that connects the SMPS to the electric outlet isn’t faulty. If possible, try replacing it with a different one and see if the issue is gone. On the other hand, if you are using a laptop, check if its battery isn’t drained out...
Each time a power MOSFET is turned on or turned off, the SMPS parasitic inductances produce ground-shift which can cause false triggering of the gate-driver ICs. Infineon's cost-effective and small gate-driver IC family protects against such consequences. The ultra-small 1.5mm x 1.1mm 6-...
EMI or EMF is a very crucial issue when a high-frequency circuit or when Switching Power Supply works on a harsh field where magnetic field radiation is an important factor such as in a power plant, near large transformers or motors, etc. ...
