Part Number: LM62440-Q1
Hi,
I have a problem where the buck seems to only be running on 100% duty cycle.
Have tried two different PCBs and different loads/ input voltages
See the pictures of the schematic and oscilloscope below.
The following pin Voltages…

Part Number: LM62440-Q1 Other Parts Discussed in Thread: LM62440EVM Hello,
The LM62440-Q1 datasheet mentions that there is a certain range of output capacitance that the internal compensation is optimized for.
What is the specific range of output capacitance…
Part Number: LM62440-Q1 Hi team,
I have a question for LM62440 MODE/SYNC pin setting.
I would like to set FPWM with Spread Spectrum ON.
In the datasheet Table.1 said it FPWM with Spread Spectrum ON can be set by Applying Vcc or >VMODE_H AND <VMODE_H2…
Part Number: LM62440-Q1 Hello,
How should I choose the Cff capacitor value?
I plan on using the adjustable output voltage option in my design (LM62440APPQRJRRQ1). The design will have 12V input and 9V output. Max output current is 2.4A. Since the duty…

Part Number: LM62440-Q1 Hi Sir,
To improve EMC products,
They connected a 10 ohm resistor between R boot and SW of lm62440-q1 chip,
And the SW pin is directly connected to the ground and has a 10pF capacitor,
In addition, a 4.7 ohm resistor is connected…
Part Number: LM62440-Q1 Hi team,
Why does LM62440-Q1 have CBOOT and RBOOT pin separately? Another DCDC converter such as LM50410-Q1 just have "CB" pin.
Could we add boot strap resistor in series to boot strap capacitor in general? Or is there…
