General Description
The EV0059 evaluation board is designed to
drive Lumileds White LEDs using MPS’
MP1567 step down converter. The EV0059
circuit is a positive to negative voltage converter
with a positive input voltage range of 2.6V to
6V. The generated output voltage can be as low
as -18V with respect to ground.
The MP1567 is a 2A peak, synchronous step
down converter utilizing a constant frequency,
current mode switching topology. The MP1567
has internal 180mΩ and 220mΩ MOSFETs and
has soft start operation. The MP1567 switches
at a high frequency (800KHz) reducing the size
of external components. It includes under
voltage lockout and over-temperature protection
and is available in the tiny 10 pin MSOP and
3mm x 3mm QFN packages.
