Part Number: LMZ14202H Hi I have a problem with LMZ14202HTZE/NOPB. I test my circuit on lab bench with power supply and works great. But when I connect 24V with a simple manual switch it turns out to burn with smoke. I measured why is that so and only…
Part Number: LMZ14202H Other Parts Discussed in Thread: LMZM33602 Hello,
we use the LMZ14202H to generate 12V for supplying of Relays and smal motors.
T he problem with the IC is that it starts to oscillate when the input voltage drops below 15V.
Or at…
Part Number: LMZ14202H Other Parts Discussed in Thread: LMZ14201H , , TL4242-Q1 I am using the LMZ14201H and LMZ142010H as a power supply in an LED lamp circuit.
The LED string current is controlled by a linear driver at constant current and we use PWM…
Part Number: LMZ14202H Hello there,
I have been designing a product around the LMZ14202H regulator. Basically, we have a product we want to operate in the range of 12-36VDC. All is well until we get to about 32VDC at which point when power is applied…
Part Number: LMZ14202H Other Parts Discussed in Thread: LMZM23601 Hi,
I am designing a multiple output dc-dc converter. The following is the spec.
Vin: 20 V-36 V, Vo1: 15 V/ 1 A, Vo2: 5 V/1 A, Vo3: -15 V/ 0.3 A.
Do you have any power module realizing multiple…
Part Number: LMZ14202H Other Parts Discussed in Thread: LMZ14202 , I'm looking for a power module that can limit its output as a function of an external input. The website says the LMZ14202 has Enable and Tracking. But I see no reference to tracking…
We have parts on both sides of the pcb, so it needs to go through reflow twice, however the data sheet says this part can only go through reflow once. How can that be? Solutions?
We have had a few failures of part number LMZ14202HTZNOPB after a couple hours of service. All of the failures are shorts that cause a fuse to blow on the board. All failures come from a date code of 1344. I ready that a process change occurred in this…
Other Parts Discussed in Thread: LMZ14202H hello everyone,
i'm facing with very annoying ripple problem.
I have two LMZ14202H modules in my circuit design, both of them gets 28v input.
one is configured for 12v, and the second for 9v
when I measure…
Other Parts Discussed in Thread: LMZ14202H Dear all
Our customer has a trouble. The output setting is 12V, but the output becomes about 2V.
The waveform is following; Yellow:RON, Green:SS, Purple:FB, Blue:OUT
I checked customer's schematic. I found that…
