REGULATED 3.3 V 200-mA LOW-NOISE
CHARGE PUMP DC/DC CONVERTER
SLVS213B – MAY 1999 – REVISED SEPTEMBER 1999
APPLICATION INFORMATION
layout
All capacitors should be soldered in close proximity to the IC. A PCB layout proposal for a two-layer board is
given in Figure 33. 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.
