SHDN (Pin 1): Logic Controlled Shutdown Input. Connect
to a voltage >1V to enable the LTC3525D. Connect to a
voltage <0.4V to disable the LTC3525D and connect VIN
to VOUT through the inductor.
GND (Pins 2, 5): Ground.
VIN (Pin 3): Input Voltage. The LTC3525D is powered from
VIN until VOUT exceeds VIN. Once VOUT is greater than (VIN
+ 0.2V typical), it is powered from VOUT. Place a ceramic
bypass capacitor from VIN to GND. A minimum value of
1F is recommended.
VOUT (Pin 4): Output Voltage Sense and the Output of the
Synchronous Rectier. Connect the output lter capacitor
from VOUT to GND, close to the IC. A minimum value of
10F ceramic is recommended. Use 22F for reduced
output ripple. The pass-through mode feature connects
VOUT to VIN through the inductor when SHDN is <0.4V.
SW (Pin 6): Switch Pin. Connect an inductor from this
pin to VIN. An internal antiringing resistor is connected
across SW and VIN after the inductor current has dropped
to zero to minimize EMI.
