Part Number: LM34904 Need to know proper value of pull up resistor that needs to be connected with Pok, to get its level at least 3.3V.
Presently with a pull up resistor of 10 k and VCC 5V, signal goes as high as 1.88V, with 5k, goes upto 2.5V on…
Hello Shravan,
A microcontroller is not required with the LM34904. The load switch can be turned on or off using the ENABLE pin, with the ACC_DET# input tied to GND. Please review the LM34904 EVM user's guide for more details, http://www.ti.com/lit…
Hello Daniel,

Hi Guy Yater,
Thanks for the response.
When I was going through http://www.ti.com/lit/sg/sszb130b/sszb130b.pdf this document & I found recommended part as TPD8E003.
So now I'm in confusion to use any one of them, Can you please suggest me , which…
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
