OZ524

FEATURES

• Supports constant voltage or constant current applications

• 3.0A continuous output current

• 0.12

Ω internal Power MOSFET

• Stable control loop

• V

OUT 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 0.12

Ω 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*V

IN using a

feedback resistor divider.
