Please see attached circuit below, and let me know about problem reason.
①About resistance of RCT pin
When customer find RCT resistance value by tester on non-12V input, it was a few MΩ.
(Datasheet is 36Ω_typ)
Addition: When 12V input, voltage is the same as Vin(12V).
⇒Is it normal operation?
②Vcc was be 1V.
Differ from datasheet spec:6.9V.
Is there find the reason?
Best regards,
