问题 1.手册 19页 “Power for the high-side and low-side MOSFET drivers and most other internal circuitry is derived from the V7V pin. The internal built-in low dropout linear regulator (LDO) supplies 6.3V (typical) from VIN to V7V. A 1μF ceramic capacitor should be connected from V7V pin to power ground.”
如果系统Vin输入为5V，是否这个V7V_LDO就不工作了？
问题2：如果系统输入是5V，MODE pin接地，出于 简单考虑，能否将EN1~3都悬空，这样3个buck的输出能否正常工作？
如果这种情况下3个buck能正常 工作，这是3者的上电顺序是否是同时上电？
