The MAX17007/MAX17008 standard application circuit
(Figure 1) generates the 1V to 1.2V/12A and 1.5V/12A
chipset voltages in a notebook computer. The input sup-
ply range is 7V to 20V for the specific application. Table 1
lists component selections, while Table 2 lists the com-
ponent manufacturers. Figure 2 shows the combined-
mode standard application circuit and Figure 3 is the
MAX17007/MAX17008 functional diagram.
The MAX17007/MAX17008 contain two constant on-
time step-down controllers designed for low-voltage
power supplies. The two SMPSs can also be combined
to operate as a two-phase high-current single-output
regulator. Constant on-time Quick-PWM operation pro-
vides fast response to load transients and handles wide

I/O voltage ratios with ease, while maintaining a rela-
tively constant switching frequency. The switching fre-
quency can be adjusted between 200kHz and 600kHz
with external resistors. Differential output current sens-
ing allows output sense-resistor sensing for an accu-
rate current-limit, lossless inductor DCR current
sensing for lower power dissipation while maintaining
0.7% output accuracy. Overvoltage (MAX17007) and
undervoltage protection and accurate user-selectable
current limits (four different levels) ensure robust opera-
tions.
The MAX17007/MAX17008 feature a special combined-
mode configuration that allows higher current outputs
to be supported. A current-balance integrator maintains
equal currents in the two phases, improving efficiency
and power distribution.
