LT8302 Not regulating Secondary correctly at +/-12V 0
Answered

Hi, I have the following circuit for the LT8302 simulated and correctly displaying +/-12V outputs but I just got prototype boards in for testing and once power was applied the LT8302 did not regulate the Secondary side of the transformer to +/-12V...

First time enabling the RUN pin, and immediate short circuit 0
Answered

Hello, We performing validation testing on a Rev A PCB. The LTC3643 is being used to hold up the 12 V rail, as the relay being used has a large in-rush current (approx. 3.6 Amps for 0.1 sec), afterwards the hold current is only 0.1 Amps. For our validation...

Burst Mode Operation 0
Not Answered

First question, is the Burst Mode Efficiency plot on page 4 really in milliamps? If so I am confused as to why 'light load' is considered only up to around1mA for this part (where the CCM and Burst Mode efficiencies become equal) whereas for LTC3636 the...

Minimum current limit of LT3042/LT3045 0
Not Answered

Is there an upper limit for RLIM for the LT3042 and the LT3045? The datasheets of the LT3042 and LT3045 do not specify a maximum value for RLIM (or minimum current limit). The "ILIM Pin Current" curve in the LT3042 datasheet starts at 20mA, but the same...

Reverse Current 0

The LTM4613 is a Buck Regulator, so that would mean we could get a reverse current flowing (via the MOSFET body diode) from output to input if Vin fell below Vout. However, I don't see anything in the datasheet that says we have to protect against this...
