Hi，team，
My customer has questions about TLV61070A,
"
TLV61070A is supplied with DC 3.3 V to output DC 5.5V.
When my customer tried to confirm the operation with the circuit for testing, the supply of DC 3.3 V damaged TLV61070A and did not work properly.
TLV61070A was damaged between VIN Vout, VIN GND and Vout GND in short circuited.
(Damaged means the resistance decreased remarkably Tens of ohms.)
The circuit has the same configuration as the circuit described in the data sheet.
The parameters they use are L1: 1.0µH，R1：100kΩ，R2:10kΩ
EN has always been in the hi state with Vin. IC is buying market goods. Detailed details such as DigiKey or Moser are not recognized.
Several chips tested have the same situation.
The contents confirmed now include
1, The output is not connected to the load, and the state is open.
2, No error with chip pin connection
3, There is no problem with circuit board fabrication
My customer wants to know:
1，what causes the chip damage,
2，Is there any special attention to using tlv61070a?
1）Voltage rise ,Inrush current
2）Reflow condition
This is very important for my customer, please give some suggestions, thank you.
Regards,
Katherine
