Configurable, Single-/Dual-Output, Synchronous
Buck Controller for High-Current Applications
General Description
The MAX15034 two-phase, configurable single- or dual-
output buck controller has an input voltage range of
4.75V to 5.5V or 5V to 28V. A mode select input allows
for a dual-output supply or connecting two phases
together for a single-output, high-current supply. Each
output channel of the MAX15034 drives n-channel
MOSFETs and is capable of providing more than 25A of
load current. The MAX15034 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 voltage ripple in dual-phase, single-output volt-
age applications. Each controller has its own high-per-
formance current and voltage-error amplifier that can
be compensated for optimum output filter L-C values
and transient response.
The MAX15034 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 MAX15034 can be synchronized to an
external clock. Each output voltage is adjustable from
0.61V to 5.5V. Additional features include thermal shut-
down and hiccup-mode, short-circuit protection. Use the
MAX15034 with adaptive voltage positioning for applica-
tions that require a fast transient response or accurate
output voltage regulation.
The MAX15034 is available in a thermally enhanced 28-
pin TSSOP package capable of dissipating 2.1W. The
device is rated for operation over the -40°C to +125°C
automotive temperature range.
