General Description

The MAX15048/MAX15049 are triple-output pulse-width  
modulated (PWM), step-down, DC-DC controllers with  
tracking (MAX15048) and sequencing (MAX15049)  
options. The devices operate over the 4.7V to 23V input-  
voltage range. Each PWM controller provides an adjustable  
output down to 0.6V and delivers up to 15A of load current  
with excellent load and line regulation. The MAX15049 can  
start into prebiased outputs. The MAX15048/MAX15049  
are optimized for high-performance, small-size power-  
management solutions.

The options of coincident or ratiometric tracking (MAX15048)  
or output sequencing (MAX15049) allow the tailoring of  
the power-up/power-down sequence depending on the  
system requirements. Each of the MAX15048/MAX15049  
PWM sections utilizes a voltage-mode control scheme with  
external compensation, allowing for good noise immunity  
and maximum flexibility with a wide selection of inductor  
values and capacitor types. Each PWM section operates at  
the same fixed switching frequency that is programmable  
from 200kHz to 1.2MHz. Each converter, operating at up to  
1.2MHz with 120Nout-of-phase, increases the input capaci-  
tor ripple frequency up to 3.6MHz, reducing the RMS input  
ripple current and thus the size of the input bypass capaci-  
tor significantly. The MAX15048/MAX15049 integrate boost  
diodes for additional system cost savings.

The MAX15048/MAX15049 include internal undervolt-  
age lockout (UVLO) with hysteresis and digital soft-start  
(MAX15048/MAX15049)/soft-stop (MAX15048) for glitch-  
free power-up and power-down of the converter. The  
power-good circuitry (PGOOD) monitors all three outputs  
and provides a power-good signal to the system control/  
processor when all outputs are within regulation. Protection  
features include lossless valley-mode current limit, hiccup  
mode output short-circuit protection, and thermal shutdown.
