LT1611
OPERATIOU
Output Current
The LT1611 will deliver 150mA at –5V from a 5V
±
10%
input supply. If a higher voltage supply is available, more
output current can be obtained. Figure 17’s schematic
shows how to get more current. Although the LT1611’s
maximum voltage allowed at V
IN
is 10V, the SW pin can
handle higher voltage (up to 36V). In Figure 17, the V
IN
pin
of the LT1611 is driven from a 5V supply, while input
inductor L
1A
is driven from a separate 12V supply. Figure
18’s graph shows maximum recommended output cur-
rent as the voltage on L
1A
is varied. Up to 300mA can be
delivered when driving L
1A
from a 12V supply.
COMPONENT SELECTION
Inductors
Each of the two inductors used with the LT1611 should
have a saturation current rating (where inductance is
approximately 70% of zero current inductance) of ap-
proximately 0.25A or greater. If the device is used in
“charge pump” mode, where there is only one inductor,
then its rating should be 0.5A or greater. DCR of the
inductors should be 0.5
or less. A value of 22
μ
H is
suitable if using a coupled inductor such as Sumida
CLS62-220 or Coiltronics CTX20-1. If using two separate
inductors, increasing the value to 47
μ
H will result in the
same ripple current. Inductance can be reduced if operat-
ing from a supply voltage below 3V. Table 1 lists several
inductors that will work with the LT1611, although this is
not an exhaustive list. There are many magnetics vendors
whose components are suitable.
