I want to use above device for following power supply.
Vin:5.4V to 6.6V
Vout:1.25V/1A
Q1:LM27341-Q1
I calculate "On Time" of following condition using equation(11),(12) of data sheet
and it is 109ns.
Vin:6.6V
Vout:1.25V
Fsw:2.3MHz
Vd1:0.5V
Rdson:0.15ohm
Iout:1A
LM27341-Q1 data sheet has "Minimum on time:65ns typical", and no maximum value.
So I can't judge if 109 ns is OK or not.
Please advice if I can use LM27341-Q1 for above application.
Q2:LM2734Z-Q1
I calculate "Duty Cycle" of following condition using equation(11),(12),
and it is 25.9%.
Vin:6.6V
Vout:1.25V
Fsw:3.6MHz
Vd1:0.5V
Rdson:0.34ohm
Iout:1A
LM2734Z-Q1 data sheet has "Minimum Duty Cycle:8% typical", and no maximums value.
So I can't judge if 25.9% is OK or not.
Please advice if I can use LM2734z-Q1 for above application.
Regards.
