OZ525 Overview

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.

Parameters

• Asymmetrical switch mode DC/DC Controller


• Voltage mode PWM control with adjustable drive output sequence


• Complementary drive architecture supporting various topologies


• Highly customizable driver sequence to minimize switching loss


• Complete protection features:


- Over-Voltage Protection (OVP) via VVD pin


- Two-level Over-Current Protection (OCP) via CS pin


- Over-Temperature (thermal) protection (OTP) via OTP pin


- Brownout Protection via BO pin


- Open loop Protection (OLP) via FB pin


- Adjustable shutdown delay timer via TIMER pin


• Fast line feed forward compensation


• Adjustable start-up delay time to reduce excessive voltage stress to power components


• User-defined soft start time


• package SOP16

Application

• General Purpose AC/DC Converter
