Part Number: LM61440 Hi Team
I am using a buck to generate the negative voltages, can i adust the output dynamically by PWM from MCU? like PWM to adjust positive BUCK output, any good idea?

Hi team,
About the Bootstrap capacitor, in datasheet, it is recommended to choose a capacitor of 100nF, I want to know what is the range of values of a capacitor? If I choose 10nF or 1uF, what will be the impact?
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 Hi team,
When customers use 61440, the output filter capacitor capacity is larger than the input filter capacitor. When powering down, the input pin VIN will power down faster than the output…
Part Number: LM61440-Q1 Hi team,
The customer uses LM61440-Q1 to power the MCU, and the MCU has requirements for the power-on time of the LM61440-Q1. At present, the power-on time of LM61440-Q1 is about 6ms, and the MCU requires 2ms. Is there anything…

Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 Dear expert,
Customer use LM61440 for both 2.1MHz and 400KHz case.
TI recommend 3*22uF capacitors for 400KHz which is too big form them. They want to know whether they can change them to…
