Part Number: TPS62933
I'm modelling a buck converter based on TPS62933 chip in Webench Power Designer. The input data is as follows: 24V in, 5V out, 0-1A output current, 1.2MHz output frequency. Everything else is in default state. When then entering…
Part Number: TPS62933 Hello,
I would like to simulate a buck converter TPS62933DRLR in the WEBBENCH Power Design.
My set parameters IN: 8.4V-12.6V to Out:6.50V @ 0.1A, Tem. 60°C
I would like to select 0.5MHz as the "use preferred frequency".…
Hello Yuto-san,
You can use webench tool to simulate the thermal Tj under different Ta and operation conditions.
If they improved 62933 layout design, the 62933 thermal could be better. You can send me layout for review.
Part Number: TPS62933 In a new design we power a microcontroller with the TPS62933 (3.3V for IO-supply and internal core voltage regulator). However, the microcontroller requires a ramp up time of min 6.5V/ms and max 30V/ms. The TPS62933 has an adjustable…
Part Number: TPS62933 My name is Oda. I have a question regarding the WEBENCH results for TPS62933.
When running WEBENCH with Vin=24V, Vout=12V, and Iout=0.4A, the recommended value of the output capacitor is 47uF. Looking at the "BILL OF MATERIALS" tab…
Other Parts Discussed in Thread: TPS62933 We have a TPS62933 in use for a 24 to 12V Buck using standard components.
This is for a volume production and in our 12 pilots we have seen 2 modes of failures.
1> When we hot plug power, we can destroy the device…
Part Number: TPS62933 Good day,
We are a few versions into prototyping a device which is able to recieve its 5v power from 2 sources. 5V from regulator output TPS62933 or 5V from USB.
Voltage is applied to the gate of mosfet Q6 when 5V is available from…
Part Number: TPS62933 Other Parts Discussed in Thread: TPS563300 ,
Hello,
1) In Table 10.2 of datasheet, the recommended inductor values are only listed for switching frequency up to 1200KHz. Is there a reference value for 2200Khz?
And for 12V output…
Part Number: TPS62933 Hi, I would like to have the following design
Input side: fixed 24VDC
Output side: use a variable resistor as the feedback high side resistor, generate variable output 1V - 17V, and 3A.
According to the Webench simulation, the TP…
Part Number: TPS62933 I'm trying to use TPS62933 to do reverse BUCK-Boost, VIN=5V, Vout=-6.6V, Iout=1A, I found that the loop is unstable when measuring the dynamic response, can you help me to calculate the CFF and output capacitance What should be done…
