Part Number:TPS54294
Dear all.
1. Vin=10.8V, Vout1=5.5V/100mA, Vout2=3.7V/1.5A
2. Vin=10.8V, Vout1=5.2V/100mA, Vout2=3.7V/1.5A
The output appears with case 2, but both output stops with case 1.
This circuit modified EVM.
3.7V : L=3.3uF 5.5V : L=4.7uF
Is the value of the inductor appropriate?
What Is the point to be careful about when I up the output voltage close to maximum duty?
Regards,
PAN-M
