MAXM17623/MAXM17624
EVALUATION KIT AVAILABLE
2.9V to 5.5V, 1A Himalaya uSLIC
Step-Down Power Modules
General Description
The Himalaya series of voltage regulator ICs and power
modules enable cooler, smaller, and simpler power-
supply solutions. MAXM17623 and MAXM17624 are
high-frequency synchronous step down DC-DC converter
modules, with integrated MOSFETs, compensation com-
ponents, and inductors, that operate over 2.9V to 5.5V
input voltage range. MAXM17623 and MAXM17624
support up to 1A load current and allow use of small, low-
cost input and output capacitors. The output voltage can
be adjusted from 0.8V to 3.3V. The modules significantly
reduce design complexity, manufacturing risks, and offer
a true plug-and-play power supply solution, reducing time-
to-market.
The MAXM17623 and MAXM17624 modules employ
peak-current-mode control architecture under steady-state
operation. To reduce input inrush current, the devices offer
a fixed 1ms soft-start time.  Both  modules feature selectable
PWM or PFM mode of operation at light loads. When
PWM mode is selected, MAXM17623 operates at a fixed
2MHz switching frequency and MAXM17624 operates at
a fixed 4MHz switching frequency. MAXM17623 offers
output voltages from 0.8V to 1.5V and MAXM17624 offers
output voltages from 1.5V to 3.3V.
The MAXM17623 and MAXM17624 modules are avail-
able in a low profile, compact 10-pin, 2.6mm x 2.1mm x
1.3mm, uSLIC™ package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”,
“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
Note 1: Junction temperature greater than +125°C degrades operating lifetimes.
Note 2: Package thermal resistance is measured on an evaluation board with natural convection.
