Other Parts Discussed in Thread: TPS60140 Why the Datasheet of the TPS60140 states (pag.4) that pin 14 must be "Not Connected" while the same datasheet at pag.15, at the same manner of Evaluation Module (pag.12 & pag.14), connects the same pin to the…
Other Parts Discussed in Thread: TPS60140 , TPS81256 Hi,
I'm working on a battery powered application, using the LM17130 battery from Saft. It has a nominal voltage of 3 V, but will drop a few hundred mV in use (depending on temperature, load etc).…
The TPS60400 is a voltage inverter, and will not help you get a boosted voltage. To boost from 2.5 V to 3.3 V, use something like the REG710-33. For 5 V, use something like the TPS60140.
What is the voltage at the LDO's input? Would it be possible to…
Hi Alexander,
Thank you for suggestion. Adding the line of code to the main section of the RF430FRL152H_NFC_Only_Project changes the VDDx2 to a constant 3.0V.
However, when I attached my circuit the voltage drops to 2.1V and the demo stops working…
Good day,
I am designing a stand alone RFID reader with a TMS3705 and a MSP430G2553, It will read at a distance of 2cm. or one inch every 3 seconds, my idea is to use a TPS61261 for the 3v3 MCU and a TPS60140 for the 5V of the TMS3705, what kind of…
Other Parts Discussed in Thread: TPS60120 , TPS61107 , TPS60140 I am trying to convert my current application with TPS60120 (200mA max) to TPS61107 to get about 280mA from two cell Ni-MH batteries (~2.4V)
TPS 61107 starts just fine at 3.3V and 140mA…
power quick search returns 39 options for charge pumps and dc/dc switching converters. More option if you want a controller w/ external FETs or a module. I would probably go with a converter or charge pump. So it will depend on your other care abouts…
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.
