XL6009
400KHz 60V 4A Switching Current Boost / Buck-Boost / Inverting DC/DC Converter
Features
General Description
n Wide 5V to 32V Input Voltage Range
n Positive or Negative Output Voltage
Programming with a Single Feedback Pin
n Current Mode Control Provides Excellent
Transient Response
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.

SW
Supply Voltage Input Pin. XL6009 operates from a 5V to 32V
DC voltage. Bypass Vin to GND with a suitably large
capacitor to eliminate noise on the input.
Feedback Pin (FB). Through an external resistor divider
network, FB senses the output voltage and regulates it. The
feedback threshold voltage is 1.25V.
