AS1361/AS1362
Datasheet - Detailed Description
The maximum power dissipation is calculated:
PDMAX = (T
J
- T
AMB
)/(
θ
JC
+
θ
CA
)
(EQ 2)
Where:
T
J
- T
AMB
is the temperature difference between the AS1361/AS1362 die junction and the surrounding air;
θ
JC
is the thermal resistance of the package;
θ
CA
is the thermal resistance through the PC board/copper traces/other materials to the surrounding air.
Note:
Pin GND of the AS1361/AS1362 provides the electrical connection to system ground and also serves as a heat
sink. Connect pin GND to the system ground using a large pad or ground plane.
Noise Reduction
The AS1361/AS1362 noise bypass circuitry dramatically reduces output noise, exhibiting 9μVRMS of output voltage
noise with C
BYPASS
= 0.01μF and C
OUT
= 1μF. Use an external 0.01μF bypass capacitor between pin BYPASS and pin
OUT
(see Figure 1 on page 1)
.
Note:
Startup time is minimized by internal power-on circuitry which pre-charges C
BYPASS
.
