The OZ525 is an energy effi cient, switched mode DC/DC controller designed for
Switched Mode Power Supply (SMPS) applications, utilizing a half-bridge topology.
High level integration and distinctive features result in a cost effective power supply
design, requiring few external components.
The controller provides complementary Pulse Width Modulation (PWM) control and
enables the designer to customize the drive sequence. Such customization, through
dedicated pins, ensures high effi ciency and performance in a power supply system
by minimizing switching loss.
