* Question
| What are the main features of MB3884? |
* Answer
| 1 The rise time and fall time of the output voltage of the three DC C converters are not freely controlled by the magnitude of the load, and therefore, it is not necessary to control the turn-on and turn-off sequence between the respective power sources by the timing control circuit.2 No current detecting Resistors is used in the synchronous rectification mode.The power supply voltage of the B3884 itself, the input supply voltage of the switching regulator, and the input supply voltage of the LD0 can be connected simultaneously or separately, regardless of the order between the three input voltages.5 The drive capability of the switching regulator main FET for the movement and the FET drive circuit for synchronous rectification. |
