Part Number: TPS62143 Needing more mA'age than USB 2.0 VBUS can supply, I'm using a TPS62143 from a 12v mains supply (PVIN connected to AVIN).
If I tie EN to 12v then all is good.
If I tie EN to VBUS (ie 5v) so I get power only when USB connected…
Part Number: TPS62143 Other Parts Discussed in Thread: TPS62147 , TPS62148 Hi,
I would like to ask you about the output voltage clamp on the TPS62143 device. The following excerpt from the data sheet shows that the VOS pin is clamped to 7.4V inside…
Part Number: TPS62143 Hi,
We are using the TPS62143 in an RFID product of ours and the DC/DC converter seems to die for no apparent reason.
We are in contact with Mike Farley at TI and so far no root cause was identified. Only a few units so far…

Part Number: TPS62143 Other Parts Discussed in Thread: TPS62142 , I am having problem with the TPS62142 and the TPS62143 failing on a system when disabled/re-enabled. We are using the recommended circuit, except the EN pin is connected to 12V and GND…
Part Number: TPS62143 Hi,
I have designed a simple PCB that regulates 14 VDC to 5 VDC using the TPS62143. I am trying to get the design FCC certified but there is a lot of EMI. Is there someone at TI who would be able to look over my design and BOM…
Part Number: TPS62143 Other Parts Discussed in Thread: TPS62147 , I recently designed a DC-DC converter using TPS62143RGTR to provide regulated 5V power from a 12V nominal (~9-15 V actual) battery. However, upon testing the circuit board, I found that…
Thanks for explaining. In the D/S, it appears to be the same package drawing:

Where do you see a different thermal pad size?
The devices have the exact same package.
Part Number: TPS62143 Other Parts Discussed in Thread: TPS62147 Hello guys,
One of our customers is evaluating TPS62143 on their own board for their new products. Then they found the TPS62143 switching frequency in CCM with FSW=L level was 2.3MHz. This…
