MAX15002
Dual-Output Buck Controller with
Tracking/Sequencing
General Description
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 ±10%. Each 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.
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 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. Each 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. Each 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.
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.
