Dual PWM Step-Down Converter in a 2mm x
2mm Package for WCDMA PA and RF Power
______________________________________________________________________________________ 15
The MAX8896 maximum power dissipation depends on
the thermal resistance of the IC package and circuit
board, the temperature difference between the die
junction and ambient air, and the rate of airflow. The
power dissipated in the device is:
P
D
= P
OUT1
x (1/?/DIV>
OUT1
- 1) + P
OUT2
x (1/?/DIV>
OUT2
- 1) +
I
LDO
x (V
OUT2
- V
LDO
)
where 穒s the efficiency of the step-down converter and
P
OUT_
is the output power of the step-down converter.
The maximum allowed power dissipation is:
P
MAX
= (T
JMAX
- T
A
)/?/DIV>
JA
where (T
JMAX
- T
A
) is the temperature difference
between the MAX8896 die junction and the surrounding
air, ?/DIV>
JA
is the thermal resistance of the junction through
the PCB, copper traces, and other materials to the sur-
rounding air.
PCB Layout
High switching frequencies and relatively large peak
currents make the PCB layout a very important part of
design. Good design minimizes excessive EMI on the
feedback paths and voltage gradients in the ground
plane, resulting in a stable and well regulated output.
Connect C
IN1
close to IN1 and PGND1 and connect
C
IN2
close to IN2 and PGND2. Connect the inductor
and output capacitor as close as possible to the IC and
keep their traces short, direct, and wide. Keep noisy
traces, such as the LX node, as short as possible. Refer
to the MAX8896EVKIT for an example layout.
