Part Number: TPS62840 Hello Team,
to program the MSP 3.3V will be connected to Vout while no input voltage connected as shown below.
Is this a problem for TPS62840?
Thank you and best regards,
Hans

HI, Previously my schematic is like this: The voltage is stable at 1.8v. Now I need to increase the voltage to 2V.
I added a 1.74k Ohm resistor as RSET. Unfortunately the voltage reading from multimeter is 1.4V.
I have double check…
Part Number: TPS62840 Hi TI team, We have included the TPS62840DLCR in our application with the following configuration:
When performing some tests in a dynamic operation mode we have observed some interesting variations in the output voltage(Vout). We…
Part Number: TPS62840 Hi, It is described that when the stop mode is enabled (STOP pin) the device temporarily stops the switching of the regulator and the application is powered by the charge available in the output capacitor. - Does it also mean that…
Part Number: TPS62840 Hi, The specs for the initial max voltage for CR2032 batteries indicate 3.4V. However, when starting draining current (i.e. 0.2mA) the voltage starts dropping to a value close to it nominal 3V. Is the TPS62840 (with input voltage up…
Part Number: TPS62840 I just received 20 PCBA from our supplier where a TPS62840YBG is used to generate 3V0 to supply power to some ICs, here attached the relative schematic sections
The issue I am facing is that the output voltage for those 20PCBA is…
Louis Colbach said: I think the STOP pin can be left floating, but you can tie it to ground to check whether it solves the issue.
Tried it on the EVK. No difference.
Louis Colbach said: I don't believe it's the output LC filter. That said, if it's feasible…
Part Number: TPS62840 Hi,
Can I set the VOS pin to Open to avoid using the discharge function? Customer don't want the discharge function, so please let me know if there is another way. Also, customer is looking for an IC that is efficient when Vin=3…
Part Number: TPS62840 Hello Team,
I see a disconnect in the specifications of quiescent current in the data sheet:
According above table Iq for VIN+VOS results in 92nA.
Looking at below graphs adding VIN+VOS at 25°C results in about 75nA.
The 75nA…
