Part Number: LM46002 Hi Sir,
We customer have some question form datasheet page 42 equation 27, PD calculator why evaluate inductor dissipation used 1.1*Iout*DCR instead of Iout*Iout* DCR.
Thanks
Rob,
It could be that the footprint/model of LM46002 has an issue or the information wasn't received by the fab house correctly. That would explain why it's only with this one device.
I've requested friendship on E2E so you can send me your circuit…
Part Number: LM46002 Hi Sir,
My customer have question for quiescent current on switching, i don't find data on datasheet only find shutdown current with junction temperature as below. can you help provide when switching active of no load status quiescent…
Part Number: LM46002 Other Parts Discussed in Thread: LM76002 Hi Sir.
My customer have one question:
The min ton is Typ 125nS, if occur SW Ｄuty less 125nS, the LM46002 have any protection mechanism？or IC do some thing to avoid??
Thanks
Summary for the E2E community:
Inverting Buck-boost converters can generate a positive voltage on the inverted output if power is suddenly applied. This causes the LM46002’s ground pins to be pulled above the chip’s BIAS pin. If the BIAS pin is connected…
Thanks for confirming what I'm seeing is normal.
In this testing I injected a signal just as suggested in the app note you recommended .
How would I do this same test on an LM46002 in the inverting mode ?
My board has an LM46002 configured for…
Part Number: LM46002 Hi Support team
My customer is having an issue with overshoot with light loads and slow ramp down of VIN.
Please see attached file for the details.

Hello Naveen,
Typically, the TRK input is not used for control for two reasons:
1) The accuracy of the TRK input is not guaranteed. Any offset in this input’s circuitry are not important during power up sequencing.
2) Since this input doubles as…
Anjana,
Your sim files has a few disconnected wires. I tried connecting them and I still got errors. I was able to create a new design in WEBENCH and export to TINA which was able to simulate. This is probably the quickest method instead of debugging…
Part Number: LM46002 Hi,
My customer connects BIAS to ground even when Vout> 3.3 V.(Iout=0-500mA,-40 to +125℃）
Does it cause damage to the device or performance deterioration?
Best regards, Seishin
