Output Ripple Consideration
SLUS582J – DECEMBER 2003 – REVISED APRIL 2009 .................................................................................................................................................. www.ti.com
Component placement should ensure that bypass capacitors (LVPB and DBP) are located as close as possible
to their respective power and ground pins. Also, sensitive circuits such as FB, RT and ILIM should not be located
near high dv/dt nodes such as HDRV, LDRV, BOOST, and the switch node (SW). Failure to follow careful layout
practices results in sub-optimal operation. More detailed information can be found in the TPS40071EVM User's
Guide (SLUU180).
In addition to the typical output ripple associated with switching converters, which can vary from 5
mV to
150 mV, the TPS40070/1 exhibits a low-frequency ripple from 5 mV to 50 mV. The ripple, a consequence of the
charge pump in the driver supply regulator, is well bounded under changes in line, load, and temperature. The
ripple frequency does vary with the converter switching frequency and can vary from 10 kHz to 60 kHz.
