connection), staying away from any high dV/dt traces.
Place the divider resistors near the LTC3703 in order to
keep the high impedance FB node short.
8. For applications with multiple switching power convert-
ers connected to the same input supply, make sure that the
input filter capacitor for the LTC3703 is not shared with

other converters. AC input current from another converter
could cause substantial input voltage ripple, and this could
interfere with the operation of the LTC3703. A few inches
of PC trace or wire (L ≅ 100nH) between C
LTC3703 and the actual source V
prevent input noise interference problems.
