Power management apparatus having an extended safe operation region and operation method thereof |
摘要 |
Two step driving technique is used to turn on the power switch of a power management apparatus in such a manner that the power switch is weakly turned on first and then goes into a low ON-resistance region. The power switch is so avoided to operate at highest gate and drain voltages simultaneously even a non-uniform turn on happens, and is thereby away from avalanche breakdown. The safe operation region of the power management apparatus is therefore extended with minimum efficiency degradation.
