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…
