Other Parts Discussed in Thread: TIDA-01405
Dear Sir/Madam,
Need technical support for TPS82130 Inverting regulator. We are using design as per TIDA-01405. See schematic below.
-AVSS = -1V7
At Power ON, first +5V (VIN) turns ON and then +3V3(Enable Line) turns ON.
At Shutdown, first +5V (VIN) is turned OFF to 0v and then after 100ms +3V3 @ Enable Pin is turned OFF to 0v. Please advise if this violates design spec of IC.
Best regards,
Felix
