Ground Connection. GND is the source terminal of the internal low-side switch. Connect all GND
bumps to a component-side PCB copper ground plane at a single point near the input bypass
capacitor return terminal.
Inductor Connection. Connect LX to the switching side of the inductor. LX is high impedance when
the MAX15112 is in shutdown mode.
Boost Input for the High-Side Switch Driver. Connect a capacitor from BST to LX.
Power-Good Open-Drain Output. PGOOD asserts high when V
deasserts when V
Remote Ground-Sense Input. Connect GSNS to the ground terminal of the load and to the bottom of
the feedback resistors.
Input Power Supply. Bypass IN to GND with at least two 22FF low-ESR ceramic capacitors with suf-
ficient ripple current ratings.
No Connection. Do not connect.
Feedback Input. Connect FB to the center tap of an external resistor divider from the output to the
output capacitor return terminal to set the output voltage from 0.6V to 0.94 x V
Skip-Mode Selector Input. Connect SKIP to EN for skip-mode operation. Connect SKIP to GND or leave
unconnected for continuous mode operation. Do not change the state of SKIP when EN is high.
Soft-Start and External Voltage Reference Input. Connect a capacitor from SS/REFIN to GND to set
the soft-start delay. See the
as an external voltage reference, apply a voltage ranging from 0V to (V
externally control the soft-start time and feedback voltage.
Filtered Input Voltage
Enable Input. Drive EN high to enable the MAX15112. Connect EN to IN for always-on operation.
Error Amplifier Output. Connect the compensation network from COMP to GND. See the
Compensation Design Guidelines
