Hi,
Mycustomer has three questions about [9.2.2.6 BIAS] of LM53603 datasheet.
=======================================================
Q1.
Is it possible to Vout is BIAScurrent any 3.3V or 5V is below 100mA by adding the resistance of 3Ω ~ 5Ω between Vout and BIAS.
I think that there is a inside circuit to limit to 100mA.
Could you tell us about it?
Q2.
When BIAS Current is 100mA, there is a voltage drop of 100mA * 5ohm = 0.5V.
When Vout = 3.3V, but is considered to Vbias is 2.8V What no problem?
Q3.It is written by datasheet.
"In severe cases, a Schottky diode can be placed in parallel with the output to limit the transient voltage and current."
Is not the problem in such a connection of attached image?
Could you tell us about the recommended value of the rated voltage and rated current and VF of the Schottky diode.
=======================================================
I'm looking forward to advice from you.
Best regards,
Watanabe
