Threaded Inserts and Heatsink Installation
CAUTION: Do not use the threaded inserts to bolt the converter down to a
PC board. That will place unnecessary force on the mounting pins. Instead,
the converter is held securely by only soldering the mounting pins.
When attaching the heat sink from above the converter, use a maximum
torque of 2 inch-pounds (0.23 N-m) on the M3 bolts to avoid damaging the
threaded inserts. Use a tiny amount of fastener adhesive or M3 lockwashers
to secure the bolts.
Heat Sinks for UCP Series
DATEL offers two standard heat sinks that can be mounted to the half-brick
package to extend the converter's operating temperature range. Along with
the standard 2.3" x 2.4" x 0.5" (HS-CP) heat sink, DATEL has designed
a low-profi le heat sink for height-restricted applications. This new heat sink
(HS-CPLP2) is designed with radiant fi ns that extend 0.51" beyond either
side of the 2.4" dimension of the BCP package. The convenience of this
design is that the fi nned extensions protrude only 0.31" below the top surface
of the DC/DC converter, allowing components with a profi le height less than
0.2" to be mounted on the pc board below the heat sink. Therefore, while
the surface area of the low-profi le heat sink measures 2.3" x 3.5", pcb real
estate is unaffected.
For optimum thermal performance in a natural convection application, the
low-profi le heat sink should be mounted with the fi ns vertically oriented. Both
models are shipped with 0.009" sellf-adhesive thermal pad and mounting
screws.
Note: When mounting the heat sink to the UCP converter:
1. Maximum applied torque is 2 in-lbs.
2. Minimum thread engagement of the mounting screws is 12mm deep.
