Part Number: LMZ14203H
Hello Support,
We are currently using the LMZ14203H to convert a +32V DC input into an 18V DC output. Our +32V bus maintains a steady state within a range of +/- 3%, although in emergency situations, it has the potential to drop…
Part Number: LMZ14203H I am using webench power designer to simulate my design. The results always have one capacitor part number on the input and one capacitor part number on the output. I need to use a combination of ceramic and tantalum polymer capacitors…
Part Number: LMZ14203H For the LMZ14203HTZ/NOPB component, we have a few questions in terms of the thermal profile of this component. In the datasheet and in SNAA214, it specifies the reflow profile for the LMZ1 and LMZ2 components, as well as the max…
Part Number: LMZ14203H Other Parts Discussed in Thread: LMZ14203 , Even if a short occurs in the LMZ14203HTZ output power, the Protection function does not operate.
Even if you forcibly short pins 1 and 2 of J19, the protection function does not work.
…
Shorting VIN and EN give s an error.

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. Any issues…
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 model…
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, RFBT…
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…
