Part Number: LM5067 Hi Team
I observed following issues in attached circuit.
1. 0.55V across UVLO/EN and VEE for the system input of -48V. Why it is not reaching 2.5V?
2. 0.4V across Gate and Source of Q4. Why it is not reaching 12V?
3. 0V across Drain…
Part Number: LM5067 Hi Ti Team, Greetings! We like to know the thermal resistance value of LM5067MM-2/NOPB. Please help us with this. Also, Kindly share the thermal model for the same.
Part Number: LM5067 Hello, Do all three items below describe the same parameters? 1) ITIMER, Fault detection current (min:-140uA/typ:-95uA/max:-44uA) described at 7.5 Electrical Characteristics of the datasheet. 2) Fault timer current source(85uA) described…
Part Number: LM5067 Other Parts Discussed in Thread: TPS23523 The power supply operates at a typical input voltage of -48V. The operating voltage range is -37V to -60V. System load varies between 120W to 200W.
I need to test the system with input voltage…
Part Number: LM5067 Hello,
My customer is using LM5067 in one -48V application, so whether we need one series resistor on OUT pin? if yes, why, and how to choose the value?
and whether it has any risk without series resistor and just ties OUT pin with…
Part Number: LM5068 Other Parts Discussed in Thread: LM5067 , , TPS23521 Hello, My customer is designing their product using the LM5068-2 to control the inrush current, and has some questions as follows. Q1: Though the current limit value can be set according…
Part Number: LM5067 Hi Guys
The slow start circuit of the system board is higher than the undervoltage protection point of the LM5067 module. After the slow start undervoltage, the input voltage rises again before the module undervoltage protection, which…
Part Number: LM5067 Hello, My customer has a couple of questions about LM5067 as follows Q1: The Itimer (Insertion time current) variation in the data sheet is large, from -9.5uA to -2.5uA. They would like to consider the temperature environment and…
Part Number: LM5067 Hi team,
My customer is using the LM5067 now. The waveform is below.
CH2 (BLUE) is the LM5067 output side, CH3(purple) is the LM5067 input side, CH4(GREEN) is the GATE of the MOSFET.
A point , LM5067 UV , gate to low, B point, LM5067 UV…
Part Number: LM5067 Other Parts Discussed in Thread: TPS23523 , Would this part survive the following during surge testing-
8/20 uS for differential mode surge +/- 1kV 2ohm and common mode surge +/- 2kV 12 ohm surge?
Thanks, Lauren
