Part Number: TPS62290-Q1 Hi Team,
Customer now use TPS62290TDRVRQ1 in their design to output 1.8V to power flash but found 5pcs abnormal when testing 40 pcs.
The abnormal is output change from 1.8V to 1.89V; SW impedance to GND change from 10M ohm to 60ohm…
Part Number: TPS62290 Hi,
Good Day. I have a customer who is working with TPS62290. Please see below his query for your reference. Thank you very much.
our application needs around 100mA of load current in maximum
so i calculated the inductor value,…
Part Number: TPS62290 Dear Teams,
Could you help check following question from my customer?
Problem: As the power input VBUS dropped from 5V to about 2.2V, the output of TPS62290DRVT changed from normal 1.15V to about 2.9V, which caused serious load heating…
Part Number: TPS62290TPS62290 problem.
My design has TPS62290 as '5V->3.3V converter'. It's well running and there is no problems, even in very high temparture test.
But when I touch the top of the chip(62290), it's going to very high temparature…
Part Number: TPS62290 Hi,
If we run the regulator at low current it will switch from PWM mode to PFM mode at MODE=low. But what would happen if we maintain the MODE pin= high, and draw very minimal current ? Will the regulator works only PWM mode ? Or…
Part Number: TPS62290-Q1 Hi Team,
I found contradiction between the text and table.
As text's meaning, MODE PIN =0, PFM mode at light load.
Is it opposite in table?
Part Number: TPS62290 Hi,
Could you please tell me the equation of acceleration factor for temperature humidity testing?
I found the equation for acceleration factor at the following URL. However, it doesn't include the humidity coefficient.
Temperature…
Part Number: TPS62290 Hi,
The response time for the EN pin depends on the load conditions, but could you please tell me the response time(the time to transition into shutdown mode and the time to return from shutdown mode) when the EN pin is asserted…
