Part Number: LM5148-Q1 Tool/software: Will injecting a test signal into the FB pin still work for gain and phase margin testing if the device is configured with a pull-up to VDDA?
If not, how can I test stability?
I'm using a 0Ω pull-up to VDDA to configure…
Part Number: LM5148 Tool/software: Hi, TI's experts:
In my design, I need to clamp a cuicuit net to about +30V volts, the diagram is shown below.
the current source have 1A out, Vo is the net I want to clamp. +45V is the system input power.
I want…
Part Number: LM5148 Other Parts Discussed in Thread: LM5145 , LM70860 Tool/software: Hello,
I am going to Design the DCDC power supply and below are the requirements

Part Number: LM5148 Hi,
Please provide internal diode structure near SW, VCC, CBOOT, HO. This will help us in designing protection for surges on SW pin in both positive and negative direction during switching.
Part Number: LM5148 Hello
I have implemented modifications to my PCB board based on discussions in the TI forum. Nevertheless, the MOSFET is encountering damage on both the high and low sides, and the PWM waveform continues to be ungenerated. I have attached…
Part Number: LM5148 Tool/software:
please refer the yellow wave is HO, purple wave is LO. VCC and VDDA is 5V, Output is 2V.
Is this may be caused by MOS type? Befroe change this new PN# MOS,out put is OK!
Part Number: LM5148 Hello：
The customer is using LM5148 for a power supply that converts 48V to 33V, with a continuous current of 2A. Currently, they are encountering two issues:
1. No output voltage, no matter how the input voltage is adjusted, there…

Customer design Dual-Phase buck, there have some question for circuit design
1. How to connect FB pin of secondary, Is it connected to the PFM/SYNC pin of primary?
2. How to chose value for CCOMP RCOMP CHF of EXTCOMP…
Part Number: LM5148 Hello,
I am using LM5148 in my design. My circuit is as shown below, the requirements:
Vin: 28V
Vout:5.5V
Iout:10A
The circuit converts 28V to 5V5. When the load is not connected to the circuit, I am measuring 5V5 at the output. But…
