⎯S⎯H⎯D⎯N (Pin 1): Logic Controlled Shutdown Input. Con-

nect to a voltage >1V to enable the LTC3525. Connect to

a voltage <0.4V to disable the LTC3525.

GND (Pins 2, 5): Ground.

VIN (Pin 3): Input Voltage. The LTC3525 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

1µF is recommended.

VOUT (Pin 4): Output Voltage Sense and the Output of the

Synchronous Rectiﬁer. Connect the output ﬁlter capacitor

from VOUT to GND, close to the IC. A minimum value of

10µF ceramic is recommended. Use 22µF for reduced

output ripple. The output disconnect feature disconnects

VOUT from VIN when ⎯S⎯H⎯D⎯N 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.
