Part Number: LM2674 Tool/software: Hi team,
The maximum switch voltage to ground is -1V. Does this mean that something like -2V is acceptable, but something like -0.1V is not? Also, the Boost pin voltage is Vsw+8V, but in my measured circuit it was…
Part Number: LM2674 Hi,
Good Day.
The customer is also for an alternative solution for the currently out-of-stock LM2674N-5.0. Requirements are fixed 5V output and should be in the same PDIP package. He also wants to know the possibility of using…
Part Number: LM2674 Hello,
We use the LM2674M-3.3 to supply micro-controllers in our products. We recently had failures at power-up resulting in blowing IC connected to the 3.3V rail (IC in short circuit). The attached pdf contains the schematic of…
Part Number: LM2674 Hi
My customer asked questions about LM2674MX-3.3
LM2674MX-3.3 is used for products in production. When 10,000 units are produced, two to three defects occur. Only defective products are being repaired because the cause has not…

Part Number: LM2674 Hello,
I got 2 question on LM2674 :
-The current limit is a peak current, rms current or average current ? If the ripple current is big the protection current can actived ? For example Io= 500mA and ripple current =1Apk_pk at 12V…
Part Number: LM2674 Hi,
I am getting a transient dip of 165mV (5V to 4.835V) during the load change from 15mA to 250mA.
I am using L=100uH,DCR=280mOhm and Cout=100uF,ESR =125mohm , Cin=47uF,ESR =125mOhm
What can be the reason for this high voltage…
