Other Parts Discussed in Thread: TPS76201 , TPS62560 Hello,
I am helping to design a lab where students use EVMs to evaluate performance metrics of power management devices. We were looking for EVMs to order for the TPS76201 LDO when I came across this…
At 4.5V Vin PGood goes off, output oscillates at 2-3KHz around 2V . if I disable downstream power converters feeding off the part (I have a TPS63030 buck-boost followed by TPS62560 buck with maybe 200mA load) things calm down and I see Pgood signal once…
Thanks again Chris
I guess the advantage is smaller package and less number of pins with the new regulators? we also have used the TPS62560, the package is small but the PWM accuracy is worse 2.5% as opposed to 1.3% for the TPS62300. any other advantage…
I looked at the datasheet's recommended output filter components (inductor and capacitor). The range of LC corner frequencies when using recommended components is between 15.7kHz and 60kHz. If you use and LC filter combination with a double pole above…
Minjae,
1) When connecting through TSW1400EVM and ADS4149EVM LVDS terminals, should both the Capture Board and ADC be connected to USB? Also, do I have to apply a clock to both ADC and Capture Board? Both boards need a USB connection as they both have…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
