Voltage-Error-Amplifier Output. Connect to the external gain-setting feedback
resistor. The error-amplifier gain-setting resistors determine the amount of
adaptive voltage positioning.
Voltage-Error-Amplifier Inverting Input. Receives a signal from the output of the
differential remote-sense amplifier (MAX5060). Connect the center tap of the
resistor-divider from the output to SGND (MAX5061).
Differential Remote-Sense Amplifier Output. DIFF is the output of a precision
unity-gain amplifier whose inputs are SENSE+ and SENSE-.
Current-Sense Differential Amplifier Negative Input. The differential voltage
between CSN and CSP is amplified internally by the current-sense amplifier
(gain = 34.5) to measure the inductor current.
Current-Sense Differential Amplifier Positive Input. The differential voltage
between CSP and CSN is amplified internally by the current-sense amplifier
(gain = 34.5) to measure the inductor current.
Differential Output-Voltage-Sensing Negative Input. SENSE- is used to sense a
remote load. Connect SENSE- to V
Differential Output-Voltage-Sensing Positive Input. SENSE+ is used to sense a
remote load. Connect SENSE+ to V

Supply Voltage for Low-Side and High-Side Drivers. Connect a parallel
combination of 0.1µF and 1µF ceramic capacitors to PGND and a 1 resistor to
V
Switching Frequency Programming and Chip-Enable Input. Connect a resistor
from RT/SYNC/EN to SGND to set the internal oscillator frequency. Drive
RT/SYNC/EN externally to synchronize the switching frequency with system
clock. If RT/SYNC/EN is held low for 50µs, the device turns off the output drivers.
Exposed Paddle. Connect the exposed paddle to a copper pad (SGND) to
improve power dissipation.
