ISL6506BI
Transistor Selection/Considerations
The ISL6506BIBZ usually requires one P-Channel and two
N-Channel MOSFETs. All three of these MOSFETs are
utilized as ON/OFF switching elements.
One important criteria for selection of transistors for all the
switching elements is package selection for efficient removal
of heat. The power dissipated in a switch element while on is
shown in Equation 2:
P LOSS = I o × r DS ( ON )
2
(EQ. 2)
Select a package and heatsink that maintains the junction
temperature below the rating with the maximum expected
ambient temperature.
Q1, Q3
These N-Channel MOSFETs are used to switch the 3.3V and
5V inputs provided by the ATX supply into the 3.3V AUX and
5V DUAL outputs while in active (S0, S1) state. The main
criteria for the selection of these transistors is output voltage
budgeting. The maximum r DS(ON) allowed at highest junction
temperature can be expressed using Equation 3:
r DS ( ON ) max = ---------------------------------------------------
V INmin – V OUTmin
I OUTmax
(EQ. 3)
where:
V INmin = minimum input voltage
V OUTmin = minimum output voltage allowed
I OUTmax = maximum output current
Q2
This is a P-Channel MOSFET used to switch the 5V SB
output of the ATX supply into the 5V DUAL output during
sleep states. The selection criteria of this device, as with the
N-Channel MOSFETs, is proper voltage budgeting. The
maximum r DS(ON) , however, has to be achieved with only
4.5V of gate-to-source voltage, so a true logic level
MOSFET needs to be selected.
