Part Number: TPS272C45 Hello,
With IEC 61000 4-6 test (conducted disturbance 10V, up to 20V, frequency between 400kHz -900kHz) output that is in the OFF state charges to some potential all the way to power supply voltage. In this case it charges to…
Part Number: TPS272C45 Hello,
We are struggle to understand datasheet regarding Latch-off mode when LATCH pin is high. From picture, a thermal shutdown appears and FLT is reset by simple toggling of EN pin. However, in the datasheet is written like…
Part Number: TPS272C45 Hello,
We are facing a strange behavior of HS switch. When it is turned off, without any capacitor at the output, it sparks after we leave it off for a ~minute.
We take a wire, and do the short connection between output and…
Part Number: TPS272C45 Hi Dear，
1-The customer uses TPS272C45D, and the initial circuit is as follows.When testing in an open or short circuit, the low level output of the FLT PIN pin is measured to be around 2V, not 0V. What is the reason？
2…
Part Number: TPS272C45 Hi team,
My customer need D version for sperate channel fault indicator. D version doesn't have Ilimtd pin for inrush current delay. What's the delay time of D version?

Part Number: TPS272C45 In the datasheet for the TPS272C45 ( Table 6-1 and 10.4.1 Layout Guidelines ), the recommendation for the external pad is to connect it to device ground for heat dissipation. Does this pad have any internal connection to ground…
Part Number: TPS272C45 Hi Dear,
1-Our customer tested TPS272C45D and found a power consumption of around 0.24W in standby mode? The test GND pin has a voltage of 0.72V, and the relevant schematic diagram is as follows.
2-The customer tested TPS27S100B…
Part Number: TPS272C45 Hello,
It is written in the datasheet that FLT will not reset until VOUTx has risen to VVS – 1.8 V.
We are keeping output shorted with a wire all the time and behavior is such that device goes in and out from fault periodically…
Part Number: TPS272C45 In the TPS272C45 12V HSD in our design, when the channel is disabled and has no load attached (Open Load + Disabled case), the output voltage from the channel toggles between 150mV and 9.5V as shown below: When I measure the enable…
Part Number: TPS272C45 Hello team, I just received a board evaluation of TPS272C45 (TPS272C45EVM).
I tried to monitor current drawn on my outputs through SNS pin. Here are my results for different currents :
SNS = :
1.61V for 2.5A 1.45V for…
