Part Number: LM46002 Hi,
the Output voltage of the LM4002 is set to +5V. But sometimes in the first 100ms after powering up the output voltage rises up to 11V. Then it slowly comes back to 5V and then it works fine.
The capacitor Cff which is parallel…
Part Number: LM46002 Dear team,
When customers were testing, 2 of their PCBs couldn't start up. The Vcc pin was 2.7V which just meet the UVLO of Vcc. If the LM46002 was blown by a heat air gun, the IC could start up. The schematic is as followed. …
Part Number: LM46002 Hi team,
As you can see in the following picture, there are two same PCBs, LM46002 in the second PCB may have some thing wrong. The Vcc has a step in the second PCB when starting up. If we put the second PCB in -40℃，the Vcc will stay…
Part Number: LM46002 Dear team,
Vin and BIAS are both input of internal LDO, why give the same 12V to Vin or BIAS, output of LDO Vcc is different? 7 out of 2 LM46002 are in this situation, they may be damaged while testing, but I want to know the theory…
Part Number: LM46002 I am using LM46002 as an inverter in order to get -12V output when Vinput = +12V. The output voltage is correctly regulated at light load condition or low loads, but when I connect 1A load the converter output (-12V) is unstable and…
Part Number: LM46002 Hello. Formula 22 in the LM46002 data sheet is yielding results that do not make sense. I am getting values much larger than expected. Can someone check this formula? It looks like there is a typo there.
Part Number: LM46002 Design:
24V In
-17V Out
0.5A max
At what load should I expect the part to drop into PFM operation? How is this affected by the switching frequency set by RT?
What amount of output capacitance should I have for -17V Out, and what…
Part Number: LM46002 I was looking at the Ap Note SNVA721A and found the suggestion about solid ground planes interesting and would like to discuss it.
Do we really think it's a good idea to have solid ground planes under the switching note and inductor…

Hi,
I've been working with LM46002PWP and have an issue with the output voltage. My input range is 9-36V, the output should be 5V. The current drawn by my load is between 330mA and 600mA. The switching frequency is 400kHz (RT = 100k…
Part Number: LM46002 Hi team,
Could you kindly advise for more detail of the OV detection function of LM46002 ?
Our customer is looking for the devices with OVP function.
Thank you and best regards,
Michiaki
