LTC1706-81
APPLICATIONS INFORMATION
When a VID input is grounded, there will be a higher
quiescent current flow from VCC because of a resistor from
VCC through a series diode to each one of the inputs. This
increase in quiescent current is calculated from:
IQ = N(VCC – VDIODE)/RPULLUP
N is the number of grounded VID inputs. VDIODE is typically
0.6V while RPULLUP has a typical pull-up resistance of
40kΩ.
In other words, each VID input has a typical pull-up current
of 68µA for a 3.3V system.
Besides the LTC1629, the LTC1706-81 also programs a
whole family of LTC DC/DC converters that have an onboard
0.8V reference. The LTC1628, LTC1735, LTC1622,
LTC1772 and LTC1929 are just a few of the high efficiency
step-down switching regulators that will work equally well
with the LTC1706-81.
