Reduce Board Space, Noise, and Power Consumption in Automotive Instrument
Clusters with Highly Integrated Power-Management IC (PMIC)
Maxim Integrated's automotive PMIC combines three high-current DC-DC
converters, saving over 50% board space compared to discrete solutions.

SAN JOSE, Calif., Feb. 18, 2014 /PRNewswire/ -- Engineers can now design
automotive clusters that are smaller, quieter, and more efficient, thanks to
the MAX16993 PMIC from Maxim Integrated Products, Inc. (NASDAQ: MXIM).
Automotive OEMs often limit instrument cluster module consumption to less than
100uA in standby mode. Given all the functions that the instrument cluster
performs, the power supply itself must consume only a tiny portion of the
power budget. Under no-load conditions, the MAX16993 is the only 3-channel
solution on the market that consumes just 25uA of quiescent current. This
makes the PMIC more efficient than traditional DC-DC converters, which often
run on several milliamps. Additionally, because the MAX16993 integrates a
high-switching-frequency controller and two output converters capable of 3A
each, it saves over 50% board space compared to traditional discrete
solutions. The device's 2.1MHz frequency improves AM band noise avoidance and
keeps the external inductors and capacitors small. The MAX16993 is ideal for
automotive instrument clusters and infotainment applications.
oSmall: integrates one high-voltage step-down controller and two 3A,
low-voltage step-down converters, saving over 50% board space compared to
oEfficient: consumes 25uA of quiescent current under no-load conditions,
meeting OEM power demands.
oQuiet: reduces AM band noise; provides a spread-spectrum enable input to
minimize radiated electromagnetic interference (EMI); includes
factory-programmable synchronization I/O to allow better noise immunity.
o"The MAX16993 offers many best-in-class features in a single chip," said
Dan Dempsey, Executive Director in the Automotive Business Unit at Maxim
Integrated. "As a result, the MAX16993 is a highly efficient automotive
power solution for today's instrument clusters."
Availability and Pricing
oThe MAX16993 is available in a 5mm x 5mm x 0.75mm, 32-pin TQFN-EP and a
5mm x 5mm x 0.8mm, side-wettable QFND-EP package.
oThe device is AEC-Q100 qualified and operates over the -40-degree to
+125-degreeautomotive temperature range.
oPricing starts at $5.39 (1000-up, FOB USA).
To ease design, a MAX16993 evaluation kit is available. Hi-res images for the
MAX16993 end application and MAX16993 block diagram are available.
