Part Number: TPS63002
I am about to give up on this Product I've replaced the part several times watched my soldering heat and still cant get it to turn off using en pin. I take the pin to GND level and the output goes to 3.5v and wont turn off. Any Idea's
Hi Kevin,Just so I know the operating conditions, could you please go through this sequence and confirm the following:
A scope plot of VIN, VOUT and EN pins during startup and including EN pulse would also be very helpful.Best regards,Milos

In reply to Milos:
Yes 4.5v from 3 AA Batteries, Load current is @ 30ma (Pic microchip, and 6 4067 cmos switches) I will work on scope plots
In reply to Kevin Pingel:
plot shows output not shutting off with en pulled low. output goes correctly to 5v when en goes high.
ch1 and ch 2 markers ar at gnd level. both channels are 1v per division.
plot below yellow is output blue is input and en is held at gnd through 1k resister. Output stabilizes at @3.3v with en at 0v.
Yellow trace on both plots is the output voltage.
Hi Kevin,I am sorry for the delay.On both plots the output voltage does not look right. On the first plot, the output voltage is almost 6 V, and on the second one is around 4 V and oscillating, and should be 5 V.
Hi Kevin,We haven’t heard back so we're assuming this resolves your issue. If not, just post a reply below, or create a new thread if the thread has locked due to time-out.Thanks and regards,Milos
