Hi Brigitte,
Thanks for your help to answer.
Hi Froylan,
Sorry for the delay. Is the 5V at the Vout supplied another power source. Under your condition, if the Vin and EN are open, the OVP is not valid, because the device is in shutdown mode. It should…

I want to set output to 5.5V, what resistor values are the best R1…
Part Number: TPS61220 Other Parts Discussed in Thread: TPS61070 I have two more questions. 4. Give me the Output Voltage Calculation Formula for TPS61220. 5. Give me the Output Voltage Calculation Formula for TPS61070.
Part Number: TPS61220
The settings for TPS61220 are as follows.
Vin 2.8~5.0V
Vout 6V
Iout 50mA
Cout:12uF
Loadtype:LED
Vsys is connected to the USB host, lithium-ion battery, and charger, and after setting EN to LOW, I think it is necessary to prevent…
Part Number: TPS61220 Other Parts Discussed in Thread: TLV61220 , TPS61222 When the output is 5.5V with TPS61220 and TLV61220, How many mA of output current can flow when the input voltage is between 0.7V and 1.5V?
Similarly, how many mA of output current…
Part Number: TPS61220 Other Parts Discussed in Thread: TPS61299 Hi Team,
Customer is using TPS61220 and need <2uA Shutdown current. But they found 20% board will have large Shutdown current than 2uA.
Their test condition is different with datasheet and…
Hi Jonathan,
Sorry for too late reply.
TPS61220 can support 2.5V to 5V/100mA condition. Maybe there is some mistakes about Webench designer setups. Thanks.

Part Number: TPS61220 Hello Wenhao,
I saw that my issue was closed due to inactivity from my side. I was not able to look into the problem because of other activities. A short update:
I checked the waveform at pin 5. It has always a high voltage, no…
