Application Information

diode by the LM3595. Power dissipation must be less than
that allowed by the package. Please refer to the Absolute
Maximum Rating of the LM3595.
INPUT CAPACITOR SELECTION
The LM3595 is designed to run off of a fixed input voltage.
Depending on the stability and condition of this voltage rail, it
may be necessary to add a small input capacitor to help filter
out any noise that may be present on the line. In the event
that filtering is needed, surface-mount multi-layer ceramic
capacitors are recommended. These capacitors are small
and inexpensive. A capacitance of 1μF is typically sufficient.
THERMAL PROTECTION
The LM3595 has internal thermal protection circuitry to dis-
able the part if the junction temperature exceeds 150C. This
feature will protect the device from damage due to excessive
power dissipation. The device will recover and operate nor-
mally when the junction temperature falls below the maxi-
mum operating junction temperature of 105C. It is important
to have good thermal conduction with a proper layout to
reduce thermal resistance.
PCB LAYOUT CONSIDERATIONS
The LLP is a leadframe based Chip Scale Package (CSP)
with very good thermal properties. This package has an
exposed DAP (die attach pad) at the center of the package
measuring 2.0mm x 1.2mm. The main advantage of this
exposed DAP is to offer lower thermal resistance when it is
soldered to the thermal land on the PCB. For PCB layout,
National highly recommends a 1:1 ratio between the pack-
age and the PCB thermal land. To further enhance thermal
conductivity, the PCB thermal land may include vias to a
ground plane. For more detailed instructions on mounting
LLP packages, please refer to National Semiconductor Ap-
plication Note AN-1187.
