OZ523 назначение, описание, схема включения

Микросхема OZ523, Производитель- O2micro®

• Supports constant voltage or constant current
• 1.5A continuous output current
• 0.25 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 protection and thermal protection

The OZ523 is a fast response PWM controller using minimum external components
to achieve control loop stability in DC/DC and LED driver applications. It supports
both constant voltage and constant current applications.
OZ523 is a non-synchronous step down DC/DC converter with a 0.25 integrated
MOSFET and supports a 1.5A continuous load current with up to 3.2A peak current.
The output voltage can be user-defi ned from 0.8V up to 0.9*VIN using a feedback
resistor divider.
OZ523 can also operate in constant current mode to drive high power LED applica-
