General Description
The MAX8655 synchronous-PWM buck regulator oper-
ates from a 4.5V to 25V input and generates an output
voltage adjustable from 0.7V to 5.5V at loads up to 25A.
Integrated power MOSFETs provide a small footprint,
ease of layout, and reduced EMI. Removing the board
trace inductances ensures the highest efficiency at
high frequency.
The MAX8655 uses peak current-mode control architec-
ture with an adjustable (200kHz to 1MHz), constant-
switching frequency, which is externally synchronizable.
The MAX8655’s adjustable current limit uses the induc-
tor’s DC resistance to improve efficiency or an external
sense resistor for higher accuracy. Foldback type cur-
rent limit is available to reduce the power dissipation
under severe-overload or short-circuit conditions. A ref-
erence input is provided for use with a high-accuracy
external reference or for DDR and tracking applications.
Monotonic startup provides safe starting into a prebi-
ased output, where traditional step-down regulators
discharge the output capacitor during soft-start, creat-
ing a negative voltage at the output and possibly dam-
aging the load.
A 180° out-of-phase synchronization output is available
for synchronizing with another MAX8655.
An enable input is provided for on/off control and to
facilitate output sequencing. Output-voltage sensing for
programmable overvoltage protection is provided and
is independent of the feedback network to further
enhance the output overvoltage protection.
Overall, the MAX8655 provides enough flexibility for the
experienced user, as well as simplicity and ease of use
for non-power-supply engineers.
