The Future of Analog IC Technology
EV0043 (MP1517)
3A, 25V, 1.1MHz
Step-Up Converter for WLED Applications
EVALUATION BOARD
DESCRIPTION
The EV1517 is the evaluation board used to
demonstrate the white LED driver capabilities of
the MP1517. The low 0.7V feedback voltage
offers higher efficiency in white LED driver
applications including cell phone camera flash.
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 voltages, output voltages
and load current conditions.
