Part Number: LM5165
Dear,
I'm using the chip LM5165YQDGSTQ1 model, and designing the PCB with a guide of the datasheet.
In LM5165 datasheet, section 8.2.2 is showing the PFM converter at 3.3V, 50mA. Then I found that PGOOD, HYS, SS pins are not…
Part Number: LM5165 Hello,
currently, we are verifying a new board using TI's LM5165 switching regulator.
After first surge test, we noticed that both swiitching regulator are dieing at a test voltage of 1kV. Both switching regulators are protected…
Part Number: LM5165 Other Parts Discussed in Thread: LM5161 , Hi
I have a power supply that requires a wide input voltage (14VDC to 50VDC) and a 12V output with a max current requirement of aoubout 50mA. The main requirement was extremely low Iq. I…
Part Number: LM5165 Hi team,
My customer considers to use LM5165 and he would like to know state of PGOOD in case of EN=L.
Which state does PGOOD become L(GND) or Hi-Z when the device is disabled?
Best regards,
Shota Mago
Part Number: LM5165 Hi All
My customer is have trouble sourcing the adjustable version of the LM5165DRC. They would like to add a series resistor into the feedback pin to get a higher voltage output. My questions are , what are the internal values…
Hi Igor,
The internal high-side feedback resistor is normally around 1M ohm range, the divider ratio of Rfb-top over Rfb_bottom is trimmed accurately but the Rfb_top or Rfb_bottom may have big tolerance, the inside resistor has different temperature…

Good morning.....
I have been reading through the above subject datasheet and have a few questions/concerns:
My application is a high voltage from Li-Ion batteries (15-21V) to 3.3V. I…
Part Number: LM5165 Datasheet (page 15) suggest when in PFM mode the inductor is tied to the switching frequency.....On page 16 the suggestion is when in COT mode Rt is tied to switching frequency.....My question is how do I come up with an inductor value…
Part Number: LM5165-Q1 Hello Team, seems that we need some clarification in our datasheet about quiescent current:
Supply current: means it that typ. and max. is only valid for TA=25 degree?
or that for TA=TJ=25 degree the typical value is 4…
