Preliminary Product Information
Synchronous Buck Converter
With Power Good Detector & LDO
The Dissipation
The power loss is given by:
P
= IO2UT1 × RDS(ON)−P × D + IO2UT1 × RDS(ON)−N ×(1− D) +VIN × IOUT1 ×(tr + t f )× fs + Is ×VIN
LOSS(DC−DC)
PLOSS(LDO) = IOUT 2 ×(VIN −VOUT 2
)
TJ (MAX ) = TA +θJA × (PLOSS (DC−DC) + PLOSS (LDO)
)
