GENERAL DESCRIPTION
The EV1517DR-00B is a MP1517 evaluation board
that is configured to provide a regulated 3.3V output
at up to 1A from a 3V to 4.2V input. The output
voltage is adjustable by changing resistors on the
evaluation board. The high 1.1MHz switching
frequency allows for smaller external components
producing a compact solution for a wide range of
load currents. Soft-start, cycle-by-cycle current
limiting, and input under voltage lockout prevent
overstressing or damage to sensitive external
circuitry at startup and output short-circuit conditions.
Current-mode regulation and external compensation
components allow the MP1517 control loop to be
optimized over a wide variety of input voltage, output
voltage, and load current conditions.
