Name Description

SS
Soft-Start Input. Place a capacitor from SS to SGND to set the soft-start period. The MP2106
sources 2μA from SS to the soft-start capacitor at startup. As the SS voltage rises, the
feedback threshold voltage increases to limit inrush current during startup.
Feedback Input. FB is the inverting input of the internal error amplifier. Connect a resistive
voltage divider from the output voltage to FB to set the output voltage value.
COMP Compensation Node. COMP is the output of the error amplifier. Connect a series RC network
to compensate the regulation control loop.
Internal 2.4V Regulator Bypass. Connect a 10nF capacitor between VREF and SGND to
bypass the internal regulator. Do not apply any load to VREF.
On/Off Control Input. Drive RUN high to turn on the MP2106; low to turn it off. For automatic
startup, connect RUN to VIN via a pullup resistor.
Power Switch Boost. BST powers the gate of the high-side N-Channel power MOSFET switch.
Connect a 10nF or greater capacitor between BST and LX.
Internal Power Input. VIN supplies the power to the MP2106 through the internal LDO
regulator. Bypass VIN to PGND with a 10μF or greater capacitor. Connect VIN to the input
source voltage.
Output Switching Node. LX is the source of the high-side N-Channel switch and the drain of the
low-side N-Channel switch. Connect the output LC filter between LX and the output.
PGND Power Ground. PGND is the source of the N-Channel MOSFET synchronous rectifier. Connect
PGND to SGND as close to the MP2106 as possible.
SGND Signal Ground.
