Part Number:TPS62742
Hello,
i'am looking for a Buck Converter with ultralow quiecent current.
The device i want to power in my application draws approx 150mA average. There are current spikes of 500mA for a few milliseconds (max 20ms / duty less than 1%) during RX activity.
At the moment iam using the LM3671 which can supply up to 600mA but draws 16uA quiecent current :(
So here are my questions:
What will happen if i draw 500mAmps from the TPS62742 in a very short period of time? The efficency is not relevant in that moment.
Is it possible that the output transistor gets damaged due to the high induction voltage or the current? Usually i suppose there may be a output voltage drop only.
Do you have an alternative ultralow quiecent current IC? Unfortunately a "shutdown" is not an option in my application.
Kind regards
Tino
