Description
Mode Input. To set the ADP2102 to Forced Continuous Conduction Mode (CCM), drive MODE high. To set the
ADP2102 to Power Saving Mode (PSM), drive MODE low.
Enable Input. Drive EN high to turn on the ADP2102. Drive EN low to turn it off and reduce the input current to 0.1μA.
This pin cannot be left floating.
Output Sense Input or Feedback Input. For fixed output versions, OUT is the top of the internal resistive voltage
divider. Connect OUT to the Output Voltage. For adjustable (non-suffix) versions, FB is the input to the error amplifier.
Drive FB through a resistive voltage divider to set the output voltage. The FB regulation threshold is 0.8V.
Analog Ground. Connect AGND to PGND at a single point as close as to the ADP2102 as possible.
Power Ground.
Switch Output. LX is the drain of the p-channel MOSFET switch and n-channel Synchronous rectifier. Connect the
output LC filter between LX and output voltage.
Power Source Input. Drive PVIN with a 2.7V to 5.5V power source.
Power Source Input. AVIN is the supply for the ADP2102 internal circuitry. For noise reduction, place an external RC
filter between PVIN and AVIN.
