Buck Controller for High-Current Applications
General Description
The MAX5066 is a two-phase, configurable single- or
dual-output buck controller with an input voltage range of
4.75V to 5.5V or from 5V to 28V. Each phase of the
MAX5066 is designed for 180° operation. A mode pin
allows for a dual-output supply or connecting two phases
together for a single-output, high-current supply. Each
output channel of the MAX5066 drives n-channel
MOSFETs and is capable of providing more than 25A of
load current. The MAX5066 uses average current-mode
control with a switching frequency up to 1MHz per phase
where each phase is 180° out of phase with respect to
the other. Out-of-phase operation results in significantly
reduced input capacitor ripple current and output volt-
age ripple in dual-phase, single-output voltage applica-
tions. Each buck regulator output has its own high-
performance current and voltage-error amplifier that can
be compensated for optimum output filter L-C values and
transient response.
The MAX5066 offers two enable inputs with accurate
turn-on thresholds to allow for output voltage sequencing
of the two outputs. The device’s switching frequency can
be programmed from 100kHz to 1MHz with an external
resistor. The MAX5066 can be synchronized to an exter-
nal clock. Each output voltage is adjustable from 0.61V to
5.5V. Additional features include thermal shutdown, “hic-
cup mode” short-circuit protection. Use the MAX5066
with adaptive voltage positioning for applications that
require a fast transient response, or accurate output volt-
age regulation.
The MAX5066 is available in a thermally enhanced 28-pin
TSSOP package capable of dissipating 1.9W. The device
is rated for operation over the -40°C to +85°C extended,
or -40°C to +125°C automotive temperature range.
