Part Number: PTR08060W Other Parts Discussed in Thread: TPSM843620 , TPSM8A28 Tool/software:
I'm trying to use a switching regulator to step 12V DC down to 2V DC, however it is not achieving this at all (even with no load connected), and is outputting…
Part Number: PTR08060W Datasheet says this modules Inhibit pin open circuit voltage is typically 2.8V. With Vin at 12V, we see 1.7V on this pin when disconnected from our circuitry. Is this normal?
Also, What's the reasoning behind the stated limitation…
Part Number: PTR08060W Hi,
The query thread "PTR08060W failures - looking for hints and ideas" which is already posted in TI forum is related to my query as well.
We are having an issue with PTR08060W. The output voltage of the module appears…
Part Number: PTR08060W The PTR08060W is drawing 50mA with no load, a 1mA resistive load, and 0.5A load. The input voltage is 10.8V and output set to 5V. A 100uF electrolytic capacitor is on the input and 100uF electrolytic is on the output. The resistor…
PTR08060 inhibit pin must either be open or controlled by an open drain FET. The inhibit has its own internal pullup voltage.
Do not connect the inhibit pin to either a pull-up voltage or another module's inhibit pin .

Other Parts Discussed in Thread: PTR08100W , PTR08060W My circuit has a 12V input and uses a PTR08060W to provide a 3.3V rail and a PTR08100W to provide a 5V rail.
The 5V and 3.3V rails are powering a bunch of circuitry including processor, USB controller…
Kevin:
The inhibit pin can only be controlled with a open drain FET. It most not be controlled with any applied voltage.
The PTR08060 controlling the output adjustment function with either a switch or potentiometer is not recommended. The voltage control…
The recommended input capacitors for:
PTh08000W 100uF capacitor is required with Rrms ripple current rating of 650mA. The suggested input capacitors are located on page 9-10 in the product specification Each capacitor should be located < 1cm from …
