Hello, We are doing an SMPS using the DCM3623T50M53C2T00 Vicor DCDC module. We need to know what is the ripple current in the external output capacitors that we must fit. Please either state it (ripple current), or comment on our method of derivation?.. PSU Spec: ???????????????. Vin is 33V Vout is 48V iout is 6A Crossover fre
Surprising that the datasheet shows several filter circuits with impedance curve, but none is specifying the inductor series resistance. Basic electric circuit knowledge clarifies however that you can't arrive at these curves without inductor series resistance (or respective external series resistance, whatever causes it).
Hello, We are doing an SMPS using the DCM3623T50M53C2T00 Vicor DCDC module. Please assist us in getting at least 10mR of ESR in our external output filter. What we currently have is as attached. PSU Spec: ???????????????. Vin is 33V Vout is 48V Pout is 288W Crossover frequency of DCM module is 20kHz. The DCM module switches at ~750kHz
Vicor seems to suggest that the modules can be well parallel operated relying on typical figures. They just suggest to balance external wire resistances. At the same time, by giving a wider range of Rout and Itrip parameters, they don't guarantee anything. It's your decision if you want to build a professional product with these devices. If y
L_Stage1 is probably tied to an external bias circuit or supply line through a lambda/4 line or RFC or similar one. Bias2 is independent bias of M6
Hi, I need to implement 1 GigE with either FPGA or ZYNQ. I am wondering performance wise which Ethernet option is more promising. 1- FPGA with external Ethernet Microcontroller (MAC and PHY) on external chip 2- ZYNQ 7020 having MAC inside the chip but it need external PHY
You have no DC supply connection to the transistor emitter, so it won't work.Look again, the circuit is fine. If you don't have one of those "digital transistors" with built-in base resistors, you need to add an external base resistor.
I have PIC16F886 4mhz crystal 1ms timer interrupt.I have code working as below. Now currently facing updating ms and Sec parameter. the min and sec parameter will update properly but not in msec and sec void interrupt isr(void) { asm("clrwdt"); if (TMR1IF) { TMR1IF = 0; // TMR1H = 0x3C; // TMR1L
Hi. I'm using ultrasclae+ . I want to use the xapp1315 in my design for 1:7 deserialization. In Xapp1315 design file, an external clock is used to enter the fpga through IBUFGDS. 157818 But in my design, there are many other logics, so xapp1315 design can not be top file. The main problem is that I have only
did you look at it with thermal camera?...see if anything getting hot...there is a good therm cam you can buy for ?150...ask me and i will tell you part number. otherwise, strip it down and see what you can get disconnect components and give the FAN6754 a dc bias voltage from external supply then see. ....take off output
I am using PIC16F886 4mhz crystal Timer1 interrupt with 1ms . i am trying to build timer application. When top display == bottom display the process should stop. Top display Set value Bottom Display shows process value. Top display set usually in time format if value 0210 means if LED_SS==0 02Sec 10ms LED_MS==0 02Min 10S LED_HM==0 02H
Hello ,I have a problem please help me.(sorry my bad english) I'm designing 3d printer control screen for marlin.I use stm32f103vgt6(HAL Lib) and stemwin for GUI.Everything is good but some varibles and uart rx interrupt register not stable.varibles changing itself and uart rx is closing itself.(initially RXNEIE = 1, then 0 why? I dont unders

I WANT TO KNOW THAT I WROTE A CODE SAVING COUNTER VALUES IN EEPROM AT24c512 BUT PROBLEM IS THAT I COULD NOT ABLE TO STORE VALUE ABOVE 255, I WANT TO STORE VALUE 0-500. PLEASE LET ME KNOW HOW TO DO? void ex0_isr (void) interrupt 0 { ex0_isr_counter++; // Increment the count by button } void main() { ex0_isr_counter = read
With your chosen CT=820pF?..that gives you ton = 20us and toff = 4us. Generally you won't use all that on_time?you will hit the current sense reference of 300mV long before basically, your buck is behaving as a constant off time buck converter with an off time of 4us?.however, your fet may be off for more than 4us in any time interval
Hi, I have a device which has a QCA6174A module like
Hi all, I have the following target to achieve and want to know what kind of circuit that I can use? Anything that can be purchased in the market directly is preferred. Thank you! 157618
I was trying to develop a simple sine wave inverter using PIC16F73 MCU.

I'm installing an electric tape fence for my horse but it's a new kind. The company sells the old kind which they call "mono-polar" and the new kind, which I have almost all installed, is called bi-polar, it carries lines for the + and the - on the same piece of tape, no ground rod, creating a shock when the horse connects the two with its muzzle o
Hi in a Yaesu FT-301 I need to connect a separate antenna on receive and a separate on transmit. I have only a coaxial going up on the roof, so I can only use a phantom power (power through the same coaxial as the signal). For the purpose, I have to use an external DC blocking capacit
