Part Number: TPS62933
Hi, I'm using 16VDC Vin (good quality, enough input current) to power up my TPS62933 board. The nominal frequency is 2.2MHz. The Vout is stable when Iout<=2.6A. When Iout>2.6A, TPS62933 turns ON and OFF rapid ly. I follow…
Part Number: TPS62933 Hi, I need a buck converter, to create a USB-C PD voltage source in range 5V to 20V, 3A of current(2,5A for 20V). I create a chematic with a TPS62933 shown bellow, but I am not sure if this driver will work fine in that conditions…
Part Number: TPS62933 Hi support team, I am considering using TPS62933 with IBB under the following conditions.
VIN: 5V VOUT: -7.5V IOUT: 500mA
Because the package thermal resistance is high, I am concerned about heat generation. I would like to calculate…
Part Number: TPS62933 Hi team,
When use tps62933 to convert 5V to 3.6V to power the measurement board (average power consumption 10mA) and display board. The terminal board, measurement board, and display board are powered on normally, and the 3.6V output…
Part Number: TPS62933
Hi,
1) Should I put current sensing resistor before or after the feedback node?
2) If I change the RT ressitor, the operating frequency will be changed. Should I change any component's value?
3) Is there any other issues for…
Part Number: TPS62933
Hi,
Vin = 24VDC, I have 2 channels
1) Vout = 5VDC. Vout decreases slightly when Iout increases. In the worst case, Vout = 3.9VDC @ 3A load
2) Vout = 12VDC. Same behavior
It was my mistake that I didn't follow the recommended layout…
Part Number: TPS62933 Hello team,
I am doing transient simulation of TPS62933 with reference test circuit of PSPICE.
However, the output voltage is unstable, and swinging about 2.2% from the VOUT set by resistor divider.
Is this because of the simulation…
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".…
