OZ524
FEATURES
• Supports constant voltage or constant current applications
• 3.0A continuous output current
• 0.12Ω internal Power MOSFET
• Stable control loop
• VOUT from 0.8V to 0.9*VIN
• Soft start function
• Fixed switching frequency
• Low current shutdown mode
• Over-current and thermal protection
GENERAL DESCRIPTION
The OZ524 is a fast response PWM controller using minimum external compo-
nents to achieve control loop stability in DC/DC and LED driver applications. It
supports both constant voltage and constant current applications. OZ524 can
operate in constant current mode to drive high power LED applications.
OZ524 is a non-synchronous step down DC/DC converter with a 0.12Ω integrat-
ed MOSFET. It supports a 3.0A continuous load current with up to 4.7A peak
current. The output voltage can be user-defined from 0.8V up to 0.9*VIN using a
feedback resistor divider.
APPLICATIONS
• General Purpose DC/DC
Converter
• High Power LED Driver
