Capacitor manufacturers continually introduce new series and offer different package styles. It is recommended
that before a design is finalized capacitor manufacturers should be surveyed for their latest product offerings.
The effective output impedance of a CAT660 circuit is
approximately:
Rcircuit
≈
Rout 660 + (4 x ESRC1) + ESRC2
CONTROLLING LOSS IN CAT660 APPLICATIONS
There are three primary sources of voltage loss:
1.
Output resistance
VLOSS
= ILOAD x ROUT, where ROUT is
the CAT660 output resistance and ILOAD is
the load current.
Charge pump (C1) capacitor ESR:
VLOSSC1 4 x ESRC1 x ILOAD, where
ESRC1 is the ESR of capacitor C1.
Output or reservoir (C2) capacitor ESR:
VLOSSC2 = ESRC2 x ILOAD, where ESRC2
is the ESR of capacitor C2.
2.
3.
Increasing the value of C2 and/or decreasing its ESR will
reduce noise and ripple.
