Triple-Output Buck Controller with  
Tracking/Sequencing  
MAX1503  
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.
