Figure 1. Standard Application Circuit
Standard Application Circuit
The standard application circuit (Figure 1) generates a
low-voltage rail for general-purpose use in a notebook
computer (I/O supply, fixed CPU core supply, DRAM
supply). This DC-DC converter steps down a battery or
AC adapter voltage to voltages from 1.0V to 5.5V with
high efficiency and accuracy.
See Table 1 for a list of component selections for com-
mon applications. Table 2 lists component manufacturers.
Detailed Description
The MAX1714 buck controller is targeted for low-voltage
power supplies for notebook computers. Maxim‘s propri-
etary Quick-PWM pulse-width modulator in the MAX1714
is specifically designed for handling fast load steps
while maintaining a relatively constant operating fre-
quency and inductor operating point over a wide range
of input voltages. The Quick-PWM architecture circum-
vents the poor load-transient timing problems of fixed-
frequency current-mode PWMs while also avoiding the
problems caused by widely varying switching frequen-
cies in conventional constant-on-time and constant-off-
time PWM schemes.
