Part Number: LMZ21700 We have a design that is using a LMZ21700 to step down an input voltage.
We have observed that if we apply +5V to EN and then some seconds later apply +5V to Vin, the part fails and is not recoverable.
The circuit only works if +5V…
Part Number: LMZ21700 I have a PCB designed with the LMZ21700SILT device. I like it for the small package due to size constraints on my board. However there is considerable audible noise associated with the 22uf input & output MLCC SMT caps (22uf, X7R…
Part Number: LMZ21700 I used the LMZ21700 in my design and now that we are trying to build our manufacturer is saying that they have had issues with soldering this part in the past. They pointed me to a study done by Flextronics about Bottom Terminated…
Part Number: LMZ21700 Hello,
I am working on a design that uses a LMZ21700 to produce a 3.3V supply voltage from an 11.1V li/po battery pack. The previous revision of the design had the EN pin of the LMZ21700 connected directly to VIN at all times, so…
Part Number: LMZ21700 Hello,
We have a customer inquiring about the plating process for this device. I am not finding anything, other than "Call TI".
From customer:
"What is the plating on the area where this gets soldered to our PCB? If gold…
Other Parts Discussed in Thread: LM2941 , LMZ21700 I am designing a small-size power circuit that uses the LM2941 Output and then inputs voltage to the LMZ21700. The Input Voltage to the LMZ21700 is approximately 14 V. These two ICs are presently very close…
Other Parts Discussed in Thread: LMZ21700 I am designing an circuit to use the LMZ21700 for an output of 5.5 V with max 0.5 A of current. Input Voltage is 14 - 17 V DC. Pg 22 of the datasheet indicates for a 5 V output V RFBT = 232K and RFBB = 44.2K. If…
Other Parts Discussed in Thread: LMZ21700 I'm using an lmz21700 in our product.
I saw a bad behavior on low input voltage.
In our application we supply the board with a rechargable lithium battery, the input range is 3.3 to 4.1V, the output voltage…
Other Parts Discussed in Thread: LMZ21700 Hi,
LMZ21700 is rated for 0.9 < Vout < 6.0 under "Recommended Operating Conditions". Using the datasheet feedback equation RFBT = RFBB x (VOUT/ 0.8 – 1), it's possible to achieve Vout = 7.1V using:…
Other Parts Discussed in Thread: LMZ21700 , LMZ21701 Hello,
Do you offer this component (LMZ21700 ) CAD information in Altium?
