MAX15003

Triple-Output Buck Controller with

Tracking/Sequencing

General Description

Features

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 10ꢀ.

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.
