Hi Excel, Thank you for your support.
I have understood that the TPS62230 does not have a specific AC voltage value for the SW pin. I will try to use newer products with defined AC tolerances whenever possible.
Best regards, Dice-K
Part Number: TPS62230 Hi Team,
Can you confirm if TPS62335 and TPS62339 are EOL already? What is our recommended alternatives if this is already EOL?
Thanks!

Part Number: TPS62230 I need information about the Peak-to-Peak Output Ripple Voltage of the TPS62237DRYR and TPS622311DRYR components. It is not specified in the datasheet.
Part Number: TPS62230 I'm sorry for asking this because I know it's a common question, but I just want to be sure. I want to prevent backfeeding the TPS62237 buck converter from a secondary power supply (I have 5 V reduced by the buck to 3.3 and…

Is it okay to briefly have 3.0V on the EN pin of the TPS62237 after voltage is removed from VIN? VIN will be removed when a cable is unplugged and it will take me about 3 mS to detect that and drive the EN pin low. I do see in the…
Part Number: TPS62230 Other Parts Discussed in Thread: AM26LV31E Hi team,
Can I apply moisture-proof coatings to these devices?

Part Number: TPS62230 Hi support team,
At startup, the inductor current is approximately 900mA for 100µsec. Is there a problem?

Part Number: TPS62230 Hi support team,
At startup, there is a partial reverse current due to the inrush current on the input side of the IC. -30 to -40mA is on the μsec order. Is there a problem?

Part Number: TPS62230 Hi support team,
The answer to the original question has the following sentence: "Hence, the SW pin lower than -0.3V should NOT be a concern if the duration is limited to several nanoseconds only."
Is there a quantitative…
