REGULATED 5ĆV 300ĆmA LOWĆNOISE
CHARGE PUMP DC/DC CONVERTER
SLVS215C − JUNE 1999 − REVISED AUGUST 2008
All capacitors should be soldered in close proximity to the IC. A PCB layout proposal for a two-layer board is
given in Figure 27. Care has been taken to connect both single-ended charge pumps symmetrically to the load
to achive optimized output voltage ripple performance. The proposed layout also provides improved thermal
performance as the exposed leadframe is soldered to the PCB. The bottom layer of the PCB is a ground plain
only. All ground areas on the PCB should be connected. Connect ground areas on top layer to the bottom layer
via through hole connections.

An evaluation module for the TPS60110 is available and can be ordered under literature code SLVP132 or under
product code TPS60110EVM−132.
