Part Number: TPS40200 Hi Team,
We would like to know a role of Zener diode between source and gate of MOSFET.
*Please refer to the D1 of Figure 31 of the datasheet.
-------
[Q1]
We understand that Zener diode protects 6pin(DRV) form Overvoltage.
Is…
Other Parts Discussed in Thread: TPS40210-Q1 , TPS40200-Q1 Dear, All
As for the datasheet of TPS40210-Q1, the operating temperature range is indicated by Tj. However, to the datasheet of buck type TPS40200-Q1, the operating temperature range is indicated…
All switching regulators are sensitive to layout, not just TPS40200. Since it is a controller, you have to layout the external FET and diode, it makes the layout more complicated. If the operation range you need is Vin=12V-48V, load = 3A max, as stated…
Hi
I can confirm it in sync with TPS62110-HT (and EP/Q1), R2 = 390K and R1 = 220K, the circuit is essentially similar to the TPS62110-HT.
The SMD resistor is 150C automotive grade and meta film type. I use same resistor for TPS40200 to 175C and did…
Dear Martin/TI FAE,
I tested this further, that is setting the current sense filter, C18 and R60 to 100nF and 2k respectively. What I found was an unwanted side effect, the PSU was not able to shutdown(OCP function) when I applied a short to the 5V output…
Knightly,
Step 1: Start with TPS40200EVM-002
Step 2: Check all components expected to VIN for >48V rating
Input Capacitors - C1 rated for 63V, C3, C4 & C8 rated for 50V
C3, C4 & C8 50V rating might be a little close. Might consider 100V…
