I have been reading the datasheet for MPM3650, however I have been unable to see a specified output voltage range. Could you please let me know the output voltage range for an input voltage of 12V with an output 4A where the IC would operate without any issues?
I am looking for an IC that can provide stable output of 5V and 8V at 3-4A.
Hello! Welcome to the MPS Technical Forum!
The output voltage range is mentioned in the recommended operating conditions section in page 4 of the datasheet.
Hi Support
Can you please explain this term “Vin x Dmax” with an example?
Hi Tim,
Vin is your input voltage, and Dmax is the maximum duty cycle.
Focusing on Dmax,
we can calculate the max duty cycle using min-off time provided in datasheet.
Tmin_off = 100ns.
Tsw = 1/fsw = 1/1.2Mhz = 833ns
Doff = Tmin_off / Tsw = ~12 %
therefore Dmax_on = 88%
Since 88% of 17V input is 14.96Vout, this falls above the specified 12Vout range. You may however, utilize this for other input ranges which result in Vout below 12V.
Best,
Nouman
thanks, it is clear for me now.
