Part Number: LM2742 Other Parts Discussed in Thread: UCC21710 Hi, I'm designing a buck converter, which a LM2742 is used to drive the low voltage side of 2 UCC21710s, as picture below shows.
I want to make sure there won't be any ground level issue…
Part Number: LM2842 Other Parts Discussed in Thread: LM2742 Hi Team，
My customer use PNP to give PWR EN signal to LM2842 SHDN PIN. The SCH is following. However, When PNP is turn-off, the voltage of PWR_EN is 0V, but LM2842's output is 3V not 0V.

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.
