Thermal Performance
The ISL8010 is available in a fused-lead MSOP10.
Compared with regular MSOP10 package, the fused-lead
package provides lower thermal resistance. The
θ
JA
is
100°C/W on a 4-layer board and 125°C/W on 2-layer board.
Maximizing the copper area around the pins will further
improve the thermal performance.
Output Voltage Selection
Users can set the output voltage of the variable version with
a resister divider, which can be chosen based on the
following formula:
Component Selection
Because of the fixed internal compensation, the component
choice is relatively narrow. For a regulator with fixed output
voltage, only two capacitors and one inductor are required. It
is recommended to use between 10μF and 22μF multilayer
ceramic capacitors with X5R or X7R rating for both the input
and output capacitors, and 1.5μH to 2.2μH for the inductor.
The RMS current present at the input capacitor is decided by
the following formula:
This is about half of the output current I
O
for all the V
O
. This
input capacitor must be able to handle this current.
The inductor peak-to-peak ripple current is given as:
L is the inductance
f
S
the switching frequency (nominally 1.4MHz)
The inductor must be able to handle I
O
for the RMS load
current, and to assure that the inductor is reliable, it must
handle the 2A surge current that can occur during a current
limit condition.
Layout Considerations
The layout is very important for the converter to function
properly. The following PC layout guidelines should be
followed:
1. Separate the Power Ground (
(
); connect them only at one point right at the pins
2. Place the input capacitor as close to V
IN
and PGND pins
as possible
3. Make the following PC traces as small as possible:
4. from LX pin to L
5. from C
O
to PGND
6. If used, connect the trace from the FB pin to R
1
and R
2
as close as possible
7. Maximize the copper area around the PGND pin
8. Place several via holes under the chip to additional
ground plane to improve heat dissipation
The demo board is a good example of layout based on this
outline. Please refer to the ISL8010 Application Brief.
