Single Quick-PWM Step-Down
Controller with Dynamic REFIN
General Description
The MAX17024 pulse-width modulation (PWM) con-
troller provides high efficiency, excellent transient
response, and high DC-output accuracy needed for
stepping down high-voltage batteries to generate low-
voltage core or chipset/RAM bias supplies in notebook
computers. The output voltage can be controlled using
the dynamic REFIN, which supports input voltages
between 0 to 2V. The REFIN adjustability combined
with a resistive voltage-divider on the feedback input
allows the MAX17024 to be configured for any output
voltage between 0 to 0.9 x V IN .
Maxim’s proprietary Quick-PWM? quick-response, con-
stant-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. Strong drivers allow the MAX17024
to efficiently drive large synchronous-rectifier MOSFETs.
The controller senses the current across the sense
resistor series with the synchronous rectifier to achieve
highly accurate valley current-limit protection.

output), and provide a predictable power-up time. The
MAX17024ETD
14 TDFN-EP* 3mm x 3mm T1433-1 ADO
controller also includes output undervoltage and ther-
mal-fault protection.
The MAX17024 is available in a tiny 14-pin, 3mm x
3mm TDFN package. For space-constrained applica-
tions, refer to the MAX17016 single step-down with 26V
internal MOSFETs capable of supporting 10A continu-
ous load. The MAX17016 is available in a small 40-pin,
6mm x 6mm TQFN package.
Note: This device is specified over the -40°C to +85°C operating
temperature range.
