Other Parts Discussed in Thread: PTN78020W , LM25088 The PTN78020W (6A, Wide voltage input) datasheet doesn't specifically call it out, but I'd like to use this in an inverting application where I apply +12V and I get out -4.2V. I'd like to get close…
Other Parts Discussed in Thread: PTN78020W I am trying to use the inhibit pin to disable the regulator output to save power on my system. I have a PTN78020W on two boards and they are both having the same issue.
The problem is that when I bring the…
Other Parts Discussed in Thread: PTN78020W Hello our current design has a PTN78020W which has two breaker relays that control the sense line and power line. We recently had an issue wear the fuse blew in the power-line and due to design limitations the…
Other Parts Discussed in Thread: PTN78020W Hi Tom,
I would like to control the output of 2 PTN78020W modules with a single potmeter conneted to the Adjust terminal, to enable an equal output voltage from both modules.
Output (Vo) of these both modules…
Other Parts Discussed in Thread: PTN78020W Hi TI team,
I have a question regarding PTN78020W. We would like to use it as a buck to convert 24V into 12V to power resistive heating elements.
Datasheet says the output current can be 0.1 to 6A.
How…
Dan::
Pin 3 is the inhibit pin control on-off function ..It can be left open or controlled by a open Drain FET. This is a low level DC voltage.
Pin 5 is a voltage adjustment .Rset pin. This pin controls the output voltage.
The unit does not have…
I have an issue with the module. When i measure on the module, I get the correct voltage (approx 9V), however, when I get on to my board (like measuring it's by pass cap), I only get approx 5.5V. Is there anything I should look for when i debug this?
Other Parts Discussed in Thread: PTN78020H , PTN78020W In the data sheet (SLTS228B) on page 13 under PTN78020W/PTN78020H Output Capacitor it says " The minimum capacitance required to ensure stability is a 330 μF. Either ceramic or electrolytic-type capacitors…
