Hi
My customer uses TPS62130.
But the SW terminal doesn't operate normal under conditions.
Could you tell me this reason?
■Spec
Vin:5V
Vout:1.2V
Iout:200mA
Fsw:2.5MHz
EN:3.3V
SS/TR:0.01uF
L:3.3uH
■situation
-Vin=5.15V, EN is assert
⇒OK
-Vin=4.85V, EN is assert.
⇒OK
-Vin=5V, EN is assert
⇒The SW terminal outputs 1 pulse, after that it isn't oscillation as 0V.
But this device operates normal by doing under some one.
・It is heated.
・The Vin waves ±150mV.
・The swittching
Best regards,
Yokota
