Part Number: LM3671-Q1 Hi E2E,
Good day.
Our customer is looking for the Total Power Dissipation (Pd) and Maximum Case Temperature (Tcmax) of LM3671QMF-1.2/NOPB and TPS560200DBVR. This information is not in the datasheet, is there a way to compute…
Other Parts Discussed in Thread: LM3671-Q1 , LM3671 , LM2734-Q1 , LM2734 , TPS62003 , TPS62260-Q1 We have a customer that really likes the efficiency, solution size and price of the LM3671 fixed output 1.25V version, but needs industrial temp. The standard…
Marc,
Please note that there is also a LM3671-Q1 part type which is an automotive qualified part. It would better suit for aerospace application because it qualified with more stringent testings. Furthermore it has Tamx=Tjmx =125C versus Tamx=85C for…
Part Number: LM3671 Other Parts Discussed in Thread: BQ24092 , Dear all:
I designed a circuit using LM3671-ADJ and followed all the recommendations described in tech. specs. For any reason , the inductor temperature is raising to a high value and is…
Part Number: LM3671 I am working on finding a date code for these parts. The bottom marking is confounding me.
So the bottom marking on 2 of them seem to indicate 2012 January and February (2A3 & 2BL). The 3rd part is marked (PAF). I cannot find a date…
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
