General Description
The XL7003 regulator is a wide input range,
current mode, DC/DC converter which is
capable of operation high input voltage up to
80V. The XL7003 built in N-channel power
MOSFET and fixed frequency oscillator,
current-mode architecture results in stable
operation over a wide range of supply and
output voltages.
The XL7003 regulator is special design for
portable electronic equipment.
