Datasheet Maxim MAX16956AUBA+ — Даташит

EVALUATION KIT AVAILABLE MAX16956 General Description The MAX16956 is a small, synchronous buck converter
with integrated high-side and low-side switches. The
device is designed to deliver up to 300mA with input
voltages from 3.5V to 36V, while using only 1.1µA
quiescent current at no load (fixed-output versions).
Voltage quality can be monitored by observing the
RESET signal. The device can operate near dropout by
running at 97% duty cycle, making it ideal for automotive
applications under cold-crank.
The device offers fixed-output voltages of 5V and 3.3V,
as well as an adjustable version. The adjustable version
allows the user to program the output voltage between
1V and 10V by using a resistor-divider. Frequency is fixed
at 2.1MHz, which allows for small external components,
reduced output ripple, and minimized AM radio interference. The device offers both forced-PWM and skip modes
of operation, with ultra-low quiescent current of 1.1µA
in skip mode. The device can be ordered with spreadspectrum frequency modulation designed to minimize
EMI-radiated emissions due to the switching frequency.
The MAX16956 is available in a small (3mm x 3mm)
10-pin µMAX® package and operates across the full automotive temperature range of -40°C to +125°C. The device
is AEC-Q100 qualified. Applications ● Automotive Body ECUs
