Hi Chris,
Thanks for the reply. I've measured the current between the battery and TPS60100 input. On a 60ohm resistive load. I expect a little over 55mA of current consumption based on simple I=V/R equation. The measurement shows around 115mA. A measurement…
This will depend on your operating requirements. Beginning on page 16 of the datasheet, the capacitor requirements are given. Only the IC and 4 capacitors are required for a complete design. A list of recommended capacitors is given on page 17.
Part Number: TPS60111 Other Parts Discussed in Thread: TPS60100 , The TPS60111PWP will intermittently not start correctly and only generate 2.8V. We have been using this part in our design for years and only recently started experiencing this issue. The…
For a boost regulator you can use an ultra-low-current charge pump such as TPS60204 or TPS60205. They have 90% efficiency and come in a 10-pin MSOP package. operating temperature is from -40 to +85 degC.
If you require synch-pins use TPS60100. But…
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…
Hello Tansel,
The UAF42 topology does not accommodate differential operation. I suggest using a multiple-feedback (MFB) active filter which lends itself nicely to a differential input, or fully differential filter. I wrote an article for TI's AAJ some…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
