Part Number: TPS61071-Q1 Hi
I have three questions about TPS61091-Q1.
1.
The VFB is typ 500mV(±10mV) at Ta=25℃ in datasheet.
Could you tell me the VFB over temperature?
2.
Is the L1 of equation (3) and (4) the maximum average inductor…
Part Number: TPS61071-Q1 Tool/software: WEBENCH® Design Tools Hi
I simulated TPS61071-Q1 under Vin=3.3V, Vout=5V, Iout=200mA by Webench.
But I couldn't simularted it because switch current limited exceeded.
I think this device can operate that…

Hello,
I need a boost converter for up converting 2.9v or 3.3v to +3.5v and -3.5v. I found in TI web-site the TPS61071 Boost converter.
In the beginning of its Datasheet it says…
Part Number: TPS61071-Q1 Hello,
for EMC reasons we want to use a 22µH inductor instead of the recommended 10µH.
The data sheet says the optimal range is up to 10µH, but higher values can also work and stability should be evaluated.
I tested and…
Yichen,
For the first revision of the design, the smaller inductor will be populated and tested. If there are issues with audible noise then the larger 4.2 mm x 4.2 mm inductor will be tried. If audible noise is still present then we'll look at using…

on page 19, the schematics for positive and negative aux voltage seem to be identical. I noticed after I…
Hello Harry
I assume that the red signal is VOUT. ——YES，The red line is the VMOT voltage signal of the LM51501-Q1
What is the blue signal? Is it the Status pin? ——The blue line is the switching voltage signal.
Why are you explicitly sowing the 1…

Hi Team,
Customer power source is CR123A battery and only needs small loading current. Output is 3.3V and 5V.
The major concern is the small ripple compared with RT9266.…
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…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
