There is voltage drop only on the input of U41 regulator, the output is stable and quiet during transmitting. I know, that this solution is working properly right now, but what bothers me is, if there isn't some factor, that I've missed, that could cause problems. Also I'm wondering, why this...
I tried the solution with separated power supply for the CAN transceivers in all devices on all pcbs and it worked, but that is not possible in some cases, because separated power supply needs another pair of wires. So I tried "filtering" and it works, but I need confirmation, that it would...
The current through the 100 ohm resistor is about 50 mA in "transmitt" state, and about 10 mA in "receive" state, so the max. power loss in resistor is 250 mW, but it is the max. instantaneous power loss, the average power loss is less than 100*((0,05+0,01)/2)^2 = 90 mW, that is nothing that...
Hi,
I have a question about power supply filtering. We have a HF system working on 8 MHz. It consists of transmitter and receiver. A couple of these devices have together power supply of 24 V. The devices are also connected with CAN bus for the communication with each other and to set...
Is there a way, even using the microcontroller, to design an universal output power supply? Say we have 12V DC input and to the output we connect a many different devices with needed power supply from 3 to 10V and with currents from 10 uA to 1A. Is there a methodology to determine the right...
I finally found a solution in TI BQ2000. A bit of playing when you need a high side current sensing, but it has an integrated switching power supply controller and a very reasonable price.
A have good experiences with ADF7020 transceiver - FSK an ASK modulation, both freq band 433 and 868 MHz for further design, both transmitter and receiver in single package, also AD has no single receiver, only transceivers, transmitter is available in package alone, but why use two different...
I've just check it and it is a very good alternative and with a lot of functionality, but the negative parameter of this IC is the price, which is almost ten times higher then of MC33340 :-(
After using battery controller MC33340 for constructing NiMH charger as a part of some portable devices for quite some time, I have found out, that this IC is no longer manufactured and a lot of IC manufacturers are ending with production of NiMH charging ICs. After a lot of hours of searching...
