High-Efficiency, 10A, PWM
Internal-Switch Step-Down Regulator
General Description
The MAX8566 high-efficiency switching regulator deliv-
ers up to 10A load current at output voltages from 0.6V
to (0.87 x V IN ). The IC operates from 2.3V to 3.6V input
supplies, making it ideal for point-of-load applications.
The total output-voltage set error is less than ±1% over
load, line, and temperature.
The MAX8566 operates in pulse-width-modulation
(PWM) mode with a 250kHz to 2.4MHz switching fre-
quency range that is programmable by an external
resistor. The IC can be synchronized to an external
clock in the same frequency range using the SYNC
input. The high operating frequency minimizes the size
of external components. Using low-R DS(ON) n-channel
MOSFETs for both high- and low-side switches main-
tains high efficiency at both heavy-load and high-
switching frequencies.
The MAX8566 employs a voltage-mode control archi-
tecture with a high-bandwidth (> 10MHz) error amplifi-
er. The voltage-mode control architecture makes
switching frequencies greater than 1MHz possible,
achieving all-ceramic-capacitor designs to minimize PC
board space. The error amplifier works with Type 3

Adjustable soft-start time provides flexibility to minimize
input startup inrush current. An open-drain, power-
good (PWRGD) signal goes high when the output
reaches 90% of its regulation point.
The MAX8566 provides a SYNCOUT output to synchro-
nize a second MAX8566 or a second regulator switch-
ing 180° out-of-phase with the first to reduce the input
ripple current, which consequently reduces the input-
