Part Number: LM62440-Q1 Tool/software: Hello experts,
My customer would like to know whether LM62440 can start-up after momentary disconnection of power.
In momentary power disconnection test, when output capacitor cannot fully discharge, can LM62440…
Part Number: LM62440-Q1 Tool/software: Hello experts,
My customer has a question regarding adjustable SW node rise time feature.
We can find the rise time at 0 ohm and 100 ohm, but customer will use 1kohm resistor.
1. Can we provide a formula of the…
Part Number: LM62440-Q1 Tool/software: Hello experts,
My customer is considering to leave RBOOT OPEN due to EMC problem.
1. Based on the description in the datasheet below, can we leave RBOOT pin OPEN(=No resistor connected)?
2. Are there any demerits…

Part Number: LM62440-Q1 Other Parts Discussed in Thread: LMQ66430 , Hi team,
I asked tEN of LMQ66430 before in E2E and found it also includes VCC start up time.
I measured from EN rising edge to the device start switching and the result was 2ms while tEN…
Part Number: LM62440-Q1 Hi team,
Could you advise if there is a mandatory requirement for minimum RFBT value of LM62440-Q1?
it is described in the datasheet below, but I would like to use below 10kohm.
"Usually RFBT is between 10 kΩ and 1 MΩ."…
Part Number: LM62440-Q1 Hi team,
There is a minimum inductor requirement equation below in LM62440-Q1 datasheet to avoid sub-harmonic oscillation.
There is also maximum inductance requirement based on minimum ripple required (K>10%) for current mode…
Part Number: LM62440-Q1 Hi team,
Could you advise configuration of MODE/SYNC pin below?
#1. Could you advise how internally biased for 2 cases below?
a. AUTO/SS-ON : 6kohm pull down to GND
b. AUTO/SS-OFF : 100kohm pull down to GND
#2. In the case of…
