GENERAL DESCRIPTION
The EV2106DQ/DK-00A is an evaluation board
designed to demonstrate the abilities of the
MP2106DQ and MP2106DK synchronous buck
converters, respectively. It can convert an input
voltage with a range of 2.6V to 15V to a lower
output voltage from 0.9V while delivering 1.5A to
the load. The output voltage is preset to 1.8V,
but can be easily be adjusted to other levels
from 0.9V.
Fault condition protection includes cycle-by-cycle
current limiting, thermal shutdown and under
voltage lockout. The part’s current mode control,
high switching frequency and integrated
high-side and low-side power MOSFETs,
combined with tiny 10-pin MSOP or QFN
packages, provide a solution requiring a
minimum of components, board area and cost.
