1.2A PWM Step-Down Converter in
2mm x 2mm WLP/UCSP for PA Power
12 ______________________________________________________________________________________
The MAX8836Z 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
DISS
= P
PA
x (1/?/DIV>
PA
- 1) + I
LDO2
x (V
IN2
- V
LDO2
)
where ?/DIV>
PA
is the efficiency of the PA step-down con-
verter and P
PA
is the output power of the PA 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 MAX8836Z die junction and the surround-
ing air; ?/DIV>
JA
is the thermal resistance of the junction
through the PCB, copper traces, and other materials to
the surrounding air.
PCB Layout
High switching frequencies and relatively large peak cur-
rents 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 IN1A/IN1B and PGND. 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.
Figure 3 illustrates an example PCB layout and routing
scheme. Note that Figure 3 does not show the common
ground plane connection of AGND and PGND. Refer to
the MAX8805W Evaluation Kit for more information.
