Part Number: LM25148-Q1 Hello support team,
Please tell me about the operation when BOOT UVLO is detected. (V BOOT-SW drops to 2.5V)
What if the VIN is low and V BOOT-SW does not recover to 2.7V?
Part Number: LM25148 Hi Team,
The customer is asking about the pull high timing of Power good pin after the device power up.
I can only find the OV and UV response time in the DS. Could you please kindly help on this? Thank you.
Part Number: LM25148 Hello,
For a design with three LM25148, we are looking to utilize the sync capabilities and spread spectrum of these devices to minimize EMI. Looking at the datasheet, it mentions that Dual Random Spread Spectrum (DRSS) is disabled…
If you lowered the frequency and did not change the inductor then the inductor pk-pk ripple current ΔIL will be very large and hit peak current limit.
The inductor pk-pk ripple current is ΔIL = T_on * (VIN-VOUT)/L.
Also T_on = (VOUT…

Could you provide or recommend proper FET or reference circuit to support 40A?
Customer already have done the evaluation for 30A with CSD18503 but there is FET damage from 35A…
