MAX15002

Dual-Output Buck Controller with

Tracking/Sequencing

General Description

Features

The MAX15002 is a dual-output, pulse-width-modulated

(PWM), step-down DC-DC controller with tracking and

sequencing options. The device operates over the input

voltage range of 5.5V to 23V or 5V 10ꢀ. ꢁach PWM

controller provides an adjustable output down to 0.6V and

delivers at least 15A of load current with excellent load

and line regulation. The MAX15002 is optimized for high-

performance, small-size power management solutions.

o Oꢂtpꢂt Voltages Adjꢂstable from ꢀ.6V to ꢀ.85V

o Lossless Valley-Mode Cꢂrrent Sensing or

ꢁN

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. ꢁach of the MAX15002 PWM sec-

tions utilizes a voltage-mode control scheme with exter-

nal compensation, allowing for good noise immunity

and maximum flexibility with a wide selection of induc-

tor values and capacitor types. ꢁach PWM section

operates at the same, fixed switching frequency that is

programmable from 200kHz to 2.2MHz and can be syn-

chronized to an external clock signal using the SYNC

input. ꢁach converter operating at up to 2.2MHz with

180° out-of-phase, increases the input capacitor ripple

frequency up to 4.4MHz, thereby significantly reducing

the RMS input ripple current and the size of the input

bypass capacitor requirement.

o Hiccꢂp Mode Short-Circꢂit Protection

The MAX15002 includes internal undervoltage lockout

with hysteresis, digital soft-start/soft-stop for glitch-free

power-up and power-down of the converter. The power-

on reset (RESET) with an adjustable timeout period moni-

tors both outputs and provides a RESET signal to the

processor when both outputs are within regulation.

Protection features include lossless valley-mode current

limit and hiccup mode output short-circuit protection.
