TLV61220: tlv61220

Ian Wang

Part Number: TLV61220

Dear Sir,

For TLV61220 inductor(4.7uH) choice, what component parameter need to pay more attention to avoid large Vout ripple?

Last customer projects using TLV61220(loading around 120mA) ripple will up to 750mV.

Thanks, Ian.

the output capacitor and the PCB layout. the output capacitor must be very closed to the IC, and the routing should be as short as possible.

Jasper,
Thanks.
For inductor, just general 4.7uH care about current, no special concern, is it?

yes.
