MAX15003
Triple-Output Buck Controller with
Tracking/Sequencing
General Description
The MAX15003 is a triple-output, pulse-width-modulat-
ed (PWM), step-down DC-DC controller with tracking
and sequencing capability. The device operates over
the input voltage range of 5.5V to 23V or 5V ±10%.
Each PWM controller provides an adjustable output
down to 0.6V and delivers up to 15A for each output
with excellent load and line regulation. The MAX15003
is optimized for high-performance, small-size power
management solutions.
The options of coincident tracking, ratiometric tracking,
and output sequencing allow the tailoring of the power-
up/power-down sequence depending on the system
requirements. Each of the MAX15003 PWM sections uti-
lizes a voltage-mode control scheme with external com-
pensation allowing for good noise immunity and
maximum flexibility with a wide selection of inductor val-
ues and capacitor types. Each PWM section operates
at the same, fixed switching frequency that is program-
mable from 200kHz to 2.2MHz and can be synchro-
nized to an external clock signal using the SYNC input.
Each converter operating at up to 2.2MHz with 120°
out-of-phase, increases the input capacitor ripple fre-
quency up to 6.6MHz, thereby reducing the RMS input
ripple current and the size of the input bypass capaci-
tor requirement significantly.
The MAX15003 includes internal input undervoltage
lockout with hysteresis, digital soft-start/soft-stop for
glitch-free power-up and power-down of each convert-
er. The power-on reset ( RESET ) with an adjustable
timeout period monitors all three outputs and provides
a RESET signal to the processor when all outputs are
within regulation. Protection features include lossless
valley-mode current limit and hiccup mode output
short-circuit protection.
