Other Parts Discussed in Thread: TPS62200 , TPS562200 What voltage could be seen across the boost cap?
Assuming Vin is 12V, the wavefrom on the SW pin is 0 to 12V switching waveform. The VBST pin presumably has a voltage already on it, so that during…
The product search engine at http://www.ti.com/lsds/ti/power-management/battery-charger-solutions-products.page#p338=NiMH&p404=Charger only shows bq24400, bq2000 and bq2002 families of NiMH buck chargers, all providing up to several amps of charger current…
Other Parts Discussed in Thread: CC430F6137 , TPS62200 Hi,
I am using CC430F6137 mcu in my application. MCU is powered by TPS62200 regulator (3V output). When CC430 is in LPM4 mode TPS62200 Enable pin is controled by CC430 (power consumption reduction…
Other Parts Discussed in Thread: TPS62200 , TPS54620 It would be nice to be able to change the feedback resistors in SwitcherPro. The text is red and bold, so it looks like it should be able to be changed. In some of the models, (many of the internally…
Hello Den,
This is a very good question.
Fundamentally the designer needs to know the current profile to determine whether a LDO or Switcher is best suited for a low power application. LDO's can have very low Iq as compared to a switcher. However…
Other Parts Discussed in Thread: TPS62200 Hi,
I want to know how the TPS76901 works at start up when the input voltage is under Vin_min=2,7V?
In my application, at start up, Vin raises from 0 to 5V.
thank you for your answer.
Other Parts Discussed in Thread: TPS62200 , BQ24032A Hi,
The problem is still a little vague but here is what we know.
We are having problems with our product not waking from sleep after charging - perhaps 1% of the units out in the field. The problem…

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…
