Part Number: LMZ14203H Hello,
I am using the LMZ14203HTZ/NOPB DC-DC converter to get 7.5V output with maximum current output of 3A from an input voltage range of 19.8V to 25.2V.
I got the circuit from the WEBENCH designer. The details of the circuit…
Part Number: LMZ14203H hi,
we are using LMZ14203H to investigate the input filter design project in ANSYS.
I am using the PSpice model of LMZ14203H and trying to simulate it in the ANSYS circuit simulator. But I have found some errors in the PSpice…
Part Number: LMZ14203H Other Parts Discussed in Thread: TLVM13630 Hello team,
Customer has used LMZ14203TZE-ADJ/NOPB and LMZ14203TXE-ADJ/NOPB on their boards. Due to recent shortages, they are thinking of using LMZ14203HTZ/NOPB as a p2p replacement…
Part Number: LMZ14203H Hi, Good day. Our customer used the LMZ14203H in their device. 28V input and 15V output. The load current is only 100ma. When the load is 100ma the LMZ14203H switching frequency is 17K When the load is 200ma the switching frequency…
Part Number: LMZ14203H Hi Team,
Our customer is trying to pass EMI testing for a medical device and they want to make sure their PCB board with LMZ14203H generates low EMI radiation. They already followed the PCB layout guidelines from the datasheet…
Part Number: LMZ14203H We have designed a PCB using 2 LMZ14203HTZE_NOPB, one for 5v (from 12V) and another for 7.4V (from 12V too). The first one is just fine, Vout is OK and the VFB is 0.8 as expected. The other one, instead of gives 7.4V it gives Vo…
Part Number: LMZ14203H Other Parts Discussed in Thread: LMZ14203 Hi Team,
Good day. We need your clarification on this query for our customer.
In Section 10.1, point number 3, of the LMZ14203 datasheet, it is mentioned that 'Both feedback resistors…
Part Number: LMZ14203H Hi
Customer designed it through WEBENCH.(Refer to below)
-SPEC-
Vin:18V / Vout:-18v
However, if the power is applied, the IC dies immediately.
I think -18V is set to GND, which is more than EN's rating. Am I right?
If…
Part Number: LMZ14203H For a voltage step-down project that accepts an input range from 28 Volts to 42 Volts I decided to use the LMZ14203H component. Respecting the design for our use :
- 28-42 V input - 12 V 3A output
We observe no problems on stabilized…
Part Number: LMZ14203H I am using LMZ14203H as a 24V regulator in my application. The part blows and shorts input to output. Once I replace the part it works OK. This has happened 5 times, in the past week.
