FUNCTION
Programmable Current-Limit Input. Connect a resistor from ILIM2 to GND to set the valley current
limit. See the Setting the Current Limit section.
Programmable Slope-Compensation Input. Internal slope-compensation voltage rate is the voltage at
SCOMP times 0.1 divided by the oscillator period (T). Connect SCOMP to AVL or GND to set to the
default of 250mV/T or 125mV/T, respectively.
Open-Drain Power-OK Output. POK goes high impedance when the output voltage rises above 91%
of the nominal regulation voltage. POK pulls low during shutdown or when the output drops below
88% of the nominal regulation voltage.
Frequency Set and Synchronization Input. Connect a resistor from FSYNC to GND to set the switching
frequency, or drive with a clock signal to synchronize between 160kHz and 1.2MHz. See the
Switching Frequency and Synchronization section.
Current-Limit Operating Mode Selection. Connect MODE to AVL for latch-off current limit or connect
MODE to GND for automatic recovery current limit.
Synchronization Output. Provides a clock output for synchronizing another MAX8655 with 180°
out-of-phase operation.
Boost Capacitor Connection. Connect a 0.22μF ceramic capacitor from BST to LXB.
LX Boost Capacitor Connection. Connect a 0.22μF ceramic capacitor between LXB and BST.
Exposed Pad. Connect to GND externally. See the Pin Configuration .
Exposed Pad. Internally connected to PVIN. See the Pin Configuration .
Exposed Pad. Internally connected to LX. See the Pin Configuration .
