LM3478: what is the diffence between 3478 and 3488

Hi Chentsu,

Below are the parameter difference between the LM3488 and the LM3478

1.Reference voltage
The LM3488 has a tighter feedback voltage rating over temperature.
2. Minimum on-time
The LM3488 has a slightly lower minimum on-time
3. Supply current
The LM3488 has a lower supply current when switching
4. Shutdown Current
The LM3488 has a lower shutdown supply current over temperature

Thanks,

Garrett
