General Description
The XL7003 regulator is a wide input range,
DC/DC converter which is capable of
operation high input voltage up to 90V. The
XL7003 built in N-channel power MOSFET
and fixed frequency oscillator results in stable
operation over a wide range of supply and
output voltages.
The XL7003 regulator is special design for
portable electronic equipment.
Applications
n EBIKE Controller Power Supply.
n High Voltage Buck Converter.
n Portable Electronic Equipment.

Description
Ground Pin.
Supply Voltage Input Pin. XL7003 VIN operates from a 10V to
90V DC voltage. Bypass Vin to GND with a suitably large
capacitor to eliminate noise on the input.
Power Switch Output Pin (SW). Output is the switch node that
supplies power to the output. The metal tab is SW.
Feedback Pin (FB). The feedback threshold voltage is 1.25V.
Supply Voltage Input Pin. A 10 μF ceramic decoupling capacitor
is required. An external voltage between 7V and 9V can be
applied to this pin to reduce internal power dissipation.
