General Description
The XL6012 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 XL6012 built in high voltage
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 XL6012 regulator is special design for
portable electronic equipment applications.
