Other Parts Discussed in Thread: TPS40304 Hi,
I have built a DC/DC-converter using Webbench and the TPS40304 switcher. The specification is Vin = 5-12V and Vout=1V Iout=5A. This Works fine for input voltages from 5-7V, but for higher input voltages it does…
Other Parts Discussed in Thread: TPS40304 , TPS40304EVM-353 Hello, I am testing with the evaluation module TPS40304 revision A. It was delivered with an 1.2Volt output Volt and 20 Amps setting.
What I changed is the FB resitor from 10K to 1k and get about…
Other Parts Discussed in Thread: TPS40304 , TPS40170 Hello,
I am curious what the gate drive performance of two similar PWM synchronous buck controllers are. I currently have a design using the TPS40304 that has the following gate drive characteristics…
Other Parts Discussed in Thread: TPS40304 Hello,
I am using a TPS40304 Buck controller in a POL circuit that converts 5VDC to 1VDC at 16A. I currently have three of these circuits on a board powering 3 different loads and 2 of the 3 seem to be working…
What is the maximum current from the BP regulator ?
I need to drive some large FETs for a 45A PSU so what is the maximum gate charge I can work with ?
Thanks
Other Parts Discussed in Thread: TPS40304 It appears that both models for the TPS40304 are wrong. I'm seeing gate drives equal to the input voltage (in this case, 14V), where they should be ~6V (since they're powered by the internal regulator). Are there…
Hello all,
I used Webench to make the circuit of a DC/DC with: - 14-14V Input.
- 7.6V Output.
- 20A Output.
But... it doesn't work, seems to have all pins with 0V but EN is about 1.5V. I made 2 different PCBs but not working. The schematic is this…
Other Parts Discussed in Thread: TPS40304 , BQ24650 Hello,
We need DCDC converter with below three functions.
-CV
-CC
-Output current is limited when Input voltage is decreased functions.
Please see the attached file as CC,CV circuit.
And please let me…
Hi Brian,
During soft-start, the DC-DC does not only provide the load current (11A), but also the charging current for the output capacitors. The average charging current is
Icharge = Vout*Cout/tss, where tss is the soft-start time set by the soft-start…
