LM62460: Schematic review for a LM62460

Hi Mirza,

Can you give some information about you application so I can confirm if the schematic is correct?

VIN range, VOUT, load, switching frequency, mode of operation,  etc.

Thanks,

Dino

Hello,

I am sorry for that.

My input can go as low as 16V and as high as 35V. But these are only short-term transients. The nominal input voltage is 24V. I am looking for a 0.4MHz switching working in PFM mode. The required output voltage is 5V 5A continous driving an ohmic load. 

The RESET pin (Pin #10) should work as power good. I have it through 100k pullup (R69). In LTSpice i made a simulation for RESETn. I approximate Open Drain as BSS84. Is that ok? Should that work? 

I model the SVIN to be output voltage of LM62460. The ODS is "RESET output with filter and delayed release" as per datasheet. The Q1, R1 and C1 is the driving circuit. and STRTn is output signal that i require. please see the attached pictures and confirm the functionality.

thank you

Hi

Thank you very much. I will update the R71. 

Can you comment on the simulation setup for RESETn pin. Is it ok to simulate RESETn as generic Open Drain or is there more to it?
