Part Number: LMZ21701 I'm puzzled.
I am bringing-up a new design with a -4.5V power supply which I get from +12V using a LMZ21701 DC-DC Nano Module in an inverting configuration. -4.5V was chosen because it fits within the 17V input limit of the LMZ21701…
Part Number: LMZ21701 Hi TI Team,
Can I leave power good pin (PG) floating if power good functionality is not required? What does TI recommend?
Thanks,

Hi Murat,
There is nothing gating the LMZ21701 from being modified into an inverting buck boost(IBB) configuration. As you might have read already, in order to generate a negative output the output voltage must be connected to ground and the ground…
Part Number: LMZ21701 Hi TI team,
I am using LMZ21701 module for Vout = 1V and Iout = 150 mA.
In this case, LMZ21701 goes to Power Save Mode (PSM) to maintain a high efficiency. In such case, I know only following two consequences:
- Switching…
Part Number: LMZ21701 Hi,
Im using on my board 3 implamentations of the LMZ21701 component for power rails: 1.8v, 2.5v and 3.3v.
This is not my first time using this switcher however first time using it for 1.8v power rail.
The problem is that I…
Part Number: LMZ21701 My application needs to step down 12V to 3.3V. I used LMZ21701 for its compact footprint. My schematic:
But output voltage is not 3.3V, instead it appears to track input voltage, Vout = Vin - 2.1V. At 12V input, I see 9.9V…

I assume for this 3300pF that you're referring to the SS (soft start) capacitor.
In this case, ESR is not of prime importance, just make sure to select a X7R or X5R capacitor, and high enough voltage rating to limit the effect of DC…
Part Number: LMZ21701 I am trying to find datecodes,
I only have what we can read on the component
I have
819BXQ
767HYQ
7RDFFQ
What are the date codes linked?
Thanks
