General Description
The MAX15035 pulse-width modulation (PWM) controller
provides high efficiency, excellent transient response,
and high DC-output accuracy. Combined with the inter-
nal low on-resistance MOSFETs, the MAX15035 pro-
vides a highly efficient and compact solution for small
form factor applications that need a high-power density.
Maxim ’s proprietary Quick-PWM ? quick-response,
constant on-time PWM control scheme handles wide
input/output voltage ratios (low-duty-cycle applications)
with ease and provides 100ns instant-on response to
load transients while maintaining a relatively constant
switching frequency. The output voltage can be dynam-
ically controlled using the dynamic REFIN, which sup-
ports input voltages between 0V to 2V. The REFIN
adjustability combined with a resistive voltage-divider
on the feedback input allows the MAX15035 to be con-
figured for any output voltage between 0V to 0.9V IN .
The controller senses the current across the synchro-
nous rectifier to achieve a low-cost and highly efficient
valley current-limit protection. External current-limit con-
trol is provided to allow higher current-limit settings for
applications with heatsinks and air flow, or for lower
current applications that need lower current-limit set-
tings to avoid overdesigning the application circuit. The
adjustable current limit provides a high degree of flexi-

The MAX15035 includes a voltage-controlled soft-start
and soft-shutdown to limit the input surge current, pro-
vide a monotonic power-up into a precharged output,
and provide a predictable soft-start time. The controller
also includes output fault protection—undervoltage and
overvoltage protection—as well as thermal-fault protec-
tion.
