Part Number: LM5148-Q1 Other Parts Discussed in Thread: LM5148 Hi,
When I am loading my supply, I can hear this clicking sound from the circuit.
My output is 23V. I am pulsing the output with a period of 20ms and 50% duty cycle
Is suspect it could be some…
Part Number: LM5148-Q1 Other Parts Discussed in Thread: LM5148 Hello!
I am using the LM5148 chip to generate 12V 10A from a 40-60V supply. My schematic is below:
I am having an issue when I restart (turn 50V input off and then on again in a short space…

Part Number: LM5148-Q1 Hi,
Please find the attached Gate pulse and Output Graph Images of a DC-DC converter :40V-60V Input, 13.8V/10A Output.
As you can see there are Transients up to 4-5V in the output when ever the MOSFET is switching, Although…
Part Number: LM5148-Q1 Hi,
We are designed a step down circuit using LM5148-Q1 as buck controller.
Vin =48V, Vout = 13.5V, Iout max 10A, Inductor used 8uH (Inductor DCR 6mOhm, Max dc current 13A)
We set the switching frequency 500KHz by Rt resistor value…
