General Description
The XL6009 regulator is a wide input range,
current mode, DC/DC converter which is
capable of generating either positive or
negative output voltages. It can be configured
as either a boost, flyback, SEPIC or inverting
converter. The XL6009 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 XL6009 regulator is special design for
portable electronic equipment applications.
Applications
n EPC / Notebook Car Adapter
n Automotive and Industrial Boost
Buck-Boost / Inverting Converters
n Portable Electronic Equipment
