Check ou the bq24185, but it only has 300mA USB OTG....probably could be pushed higher if needed. Is the 500mA needed for peak current or continuous current?
You can not use it for more than 10.5V. You can consider other part such bq24185.
OK, based on your description, it is a different path management that the IC is doing. Dynamic power path management is well explained in the datasheet on page 17-19…
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.
