TPS562242: Request to review the circuit

I understand that the input voltage should be over 3.7v.  Input voltage  range will be 3.9v ~6.5v.

Please review the circuit  if there is no problem except input voltage and check the inductor value is ok  and recommebd which part is ok .

Dear Sir,

No problem. I will check and get back to you during these days. Thank you!

Hi Lucia,

I am waiting your feedback, Your quick reply would be very appreciated.

Please first check the inductor value and recommend it.

Hi Beom,

Sorry for late. I will review soon

Hi Lucia, 

 I am waiting for your review result for the  TPS562242 circuit schematic.

When can I get your review result ?

 Please let me know if the schematic and the inductor is ok or not ASAP.

Dear  Lucia,

Thanks for your reply.

The Input voltage set to minimum 4.0v and use the TPS562242 .

 If so, the duty is 93% ( the output voltage is 3.7v)

And  for the feedback resistor, I will set the value, bottom resistor (R38) is 24.9k, top resistor(R37) is 91k  as your recommend.

 Please check if the top and bottom resistor value is ok or not.

 And also check if R10 resistor value 0 ohm is ok or not in my TPS562242 schematic .

 If not, R10 resistor value should be 51 ohm as your EVM board circuit.

And  in my TPS562242 schematic ,the other is ok except above item.

Dear Lucia,

Thanks for your support.
