OCP8153

高精度原边反馈恒流转换器

典型应用电路

图一，

OCP8153 典型应用电路

概述

OCP8153 是一款集成了 650V MOSFET 高精度离

线式

LED 恒流驱动芯片，可应用于输出功率 10W 以内

的

LED 恒流驱动电源，支持全电压输入 AC85V~265V。

芯片支持封装形式：

DIP-8L，利用原边反馈技术，

无需

TL431、光耦和反馈电路便能实现很好的线电压调

整率和负载调整率，极大的节约了系统成本和尺寸空间。

OCP8153 具备完善的保护功能，其利用 VCC 脚进

行过压检测，一旦检测到过压信号芯片便进入打嗝工作

状态；芯片利用

FB 管脚实现了短路检测，一旦发现短路

信号芯片便会进入较低的工作频率以限制输出功率，同

时芯片还具备

LED 开短路保护、FB 短路保护、欠压锁

定和过温保护功能以保证整个系统在恶劣的工作环境中

安全可靠的工作。
