THERMAL INFORMATION
thermally enhanced TSSOP-20 (PWP PowerPad
) (continued)
The thermal pad is directly connected to the substrate of the IC, which for the TPS752xxQPWPEP and
TPS754xxQPWPEP series is a secondary electrical connection to device ground. The heat-sink surface that is
added to the PWP can be a ground plane or left electrically isolated. In TO220-type surface-mount packages, the
thermal connection is also the primary electrical connection for a given terminal which is not always ground. The
PWP package provides up to 16 independent leads that can be used as inputs and outputs (Note: leads 1, 10, 11,
and 20 are internally connected to the thermal pad and the IC substrate).
