DESCRIPTION
The EV3212DQ-00A is the evaluation board of
MP3212, a constant frequency, 10-pin QFN
current mode step-up converter intended for
small, low power applications. The EV3212DQ
operates from an input voltage as low as 2.3V
and can generate as high as 28V output voltage
and up to 100mA output current.
The EV3212 features PFM at light loads for
high efficiency. The EV3212 includes under-
voltage lockout, output over-voltage protection,
current limiting, and thermal overload protection
to prevent damage in the event of an output
overload.
