When OFFSET is enabled, the MAX17080 enables a fixed +12.5mV offset on SMPS1 and SMPS2
VID codes after PGD_IN goes high. This configuration is intended for applications that implement a
load line. An external resistor at FBDC_ sets the load-line. The offset can be disabled by setting
the PSI_L bit to 0 through the serial interface.
Additionally, the OPTION level also allows core SMPS1 and SMPS2 to take on either the VDD0 or
VDD1 addresses. VDD0 refers to CORE0, and VDD1 refers to CORE1 for the AMD CPU.
The NB SMPS is not affected by the OPTION setting.
Oscillator Adjustment Input. Connect a resistor (R OSC ) between OSC and GND to set the switching
frequency (per phase):
f OSC = 300kHz x 143k /R OSC

OSC
A 71.4k
to 432k
corresponds to switching frequencies of 600kHz to 100kHz, respectively, for
SMPS1 and SMPS2. SMPS3 runs at twice the programmed switching frequency. Switching frequency
selection is limited by the minimum on-time. See the Core Switching Frequency description in the
SMPS Design Procedure section.
Slew-Rate Adjustment Pin. The total resistance R TIME from TIME to GND sets the internal slew rate:
PWM slew rate = (6.25mV/μs) x (143k /R TIME )
where R TIME is between 35.7k
and 357k .

This slew rate applies to both upward and downward VID transitions, and to the transition from boot
mode to VID mode. Downward VID transition slew rate in skip mode can appear slower because the
output transition is not forced by the SMPS.
The slew rate for startup is fixed at 1mV/μs.
Exposed Pad. Power ground connection, and source connection of the internal low-side MOSFET.
