Hi
My customer configured an external circuit for OCP operation using op-amp. The way it works is to lower the KFF pin to low when it becomes OCP. My customer asked if it works like the waveform below.
<Ch1(yelow):Vgs, Ch2…
Part Number: TPS40055 Other Parts Discussed in Thread: LM5146 , LM5145 , I have an application in which Voltage Feedforward needs to be disabled due to limitation of maximum duty cycle as a result of programmable UVLO.

Part Number: TPS40055 Other Parts Discussed in Thread: TPS40057 Hello TI experts,
My customer now check the schematic of TPS40055. Could you review the schematic first?
and they have a problem that sometimes the output is not detected even input…
Part Number: TPS40055 Hi
There is usually resistance to the GATE of MOSFET.
However, there is no gate resistance in the circuit of the TPS40055.
Why is there no resistance?
Thanks
Part Number: TPS40055 Hi Team,
Can you please help us with our customer's inquiry below?
I n datasheet page 5 test conditions "TA = –40°C to 85°C, VIN = 24 Vdc, RT = 90.9 kΩ, IKFF = 150 μA, fSW = 500 kHz, all parameters at zero power dissipation"…
Part Number: TPS40055 Other Parts Discussed in Thread: LM25145 , LM5146 , LM5145 Is there a P2P replacement scheme for tps40055pwp? The current and voltage can be different. Our customers use this IC, but they can't buy it at present and are eager to…
