LMS3655: Datasheet page 8 qustion

Alan Hong

Part Number: LMS3655

For LMS3655 data sheet,

Page 8 , Iq_vin , imply that the spec for Vin= 13.5V Vout =3.3V , and Vin = 13.5V Vout=5.0V , and parameter are equal to 32 and 57 uA respectively.

Our hardware team need know the design condition , if Vin =24V , Vo=12V and Vin = 24V , Vo = 5V

How the Iq_vin = ? uA respectively ?

Please tell me the result and email to alan_hong@quantatw.com

Thanks.

I will check with the engineer that worked on this and see if we have this data.

Any update for 24V to 12V , like as page 8 test criteria ?

Please give me a reponse asap to let me reply our customer.

We will take this data by the end of next weed; once we get an EVM in house.

We have gathered the following data on the EVM with the specified FB resistor:

Iq = 22uA, Vin = 24V, Vout = 5V, Rfbt=1M
Iq = 40uA, Vin =24V, Vout = 12V, Rfbt=1M
Iq = 40uA, Vin = 24V, Vout = 5V, Rfbt=49.9k
Iq = 156uA, Vin =24V, Vout = 12V, Rfbt=49.9k
