OZ525 Asymmetrical LLC DC/DC Controller
Features
POWER MANAGEMENT ICs
The OZ525 is an energy efficient, switched mode DC/DC controller designed for Switched Mode Power Supply (SMPS) applications, using 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 that enables the designer to customize the drive sequence. Such customization, through dedicated pins, ensures high efficiency and performance in a power supply system by minimizing switching loss.
