Standard Application Circuit
The MAX17024 standard application circuit (Figure 1)
generates a 1.5V or 1.05V output rail for general-purpose
use in a notebook computer. Table 1 lists the compo-
nent manufacturers.
Detailed Description
The MAX17024 step-down controller is ideal for the
low-duty-cycle (high-input voltage to low-output volt-
age) applications required by notebook computers.
Maxim’s proprietary Quick-PWM pulse-width modulator
in the MAX17024 is specifically designed for handling
fast load steps while maintaining a relatively constant
operating frequency and inductor operating point over
a wide range of input voltages. The Quick-PWM archi-
tecture circumvents the poor load-transient timing
problems of fixed-frequency, current-mode PWMs while
also avoiding the problems caused by widely varying
switching frequencies in conventional constant-on-time
(regardless of input voltage) PFM control schemes.
