Dear TI
Regarding voltage reference on datasheet page3,
Voltage is 0.804V at the Pulse Skip mode and 0.800V at continuous current mode as typical.
So Vout in pulse skip mode is 0.5% higher than continuous current mode.
But at load regulation graph…
Satya,
So far as I can tell, TPS62111 is only available as a QFN. It should be marked as:
TPS
62111
TI YMS
LLLL
Where:
Y = year
M = month
S = fab site
LLLL = lot code.
We do have a DC/DC converter in 5 pin SOT package, TPS560200…
Hi Ryan,
Thank you for your respond, that was really helpful. I wasn't considering the inductor's saturation current in that situation. It was around 1.5 A as i was using lighter loads around 500 mA. I will use a lower rating device such as TPS560200…
Dear Roberto,
Good Morning!
I have used same TPS560200 Buck convertor, and I load +5V output with 75mA (here microcontroller and LCD card are not connected). Above readings are with 75mA load connected. Is this load is enough? or should I increase…
Part Number: TPS62992-Q1 Other Parts Discussed in Thread: TPS560200-Q1 , , TPS62901-Q1 Hello, colleagues,
The TPS62901-Q1 specifies a maximum Start-up delay time of 1400 µs or 1850 µs depending on the configuration. But further on the Soft-start time…
Hi Naveen,
There is a lot here, let me try to suggest the best parts for each section:
1. For the battery charger - BQ24610 should work
2. 18V to 12V / 4.5A - LM61460 will work well
3. 12V to 3.3V / ?A - I assume the current is fairly low here…
I can not tell you the total loss, Robson, however the efficiency of the converter is ~88%.
TPS560200 is a synchronous buck converter, the most efficient of the buck converters.
To calculate total loss you would need to precisely know the load current…
Rayna,
The regulator output is very noisy with minimum around 3v. It's possible that a current spike is dropping it low enough to trip the device because the minimum is already at 3v. They should look into cleaning up the output of the regulator because…
Dear Denislav
Thank You for your reply. We have changed our design to use TPS560200-Q1 to achieve 3.3V( https://e2e.ti.com/support/power-management/f/power-management-forum/998267/tps560200-q1-design-advice/3688725#3688725 )
THe 5V was to going…
