NOTES: (1) The Zener Impedance is derived from the 1kHz AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (IZT or IZK) is superimposed on IZT or IZK. Zener Impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. (2) Measured with device junction in thermal equilibrium.

QX5248规格书

QX5248规格书概述QX5248是一款高集成度、高性能的电流模式PWM控制器芯片。

适用于笔记本电源等中大功率的开关电源设备。

极低的启动电流与工作电流、以及轻载或者无负载情况下的脉冲模式功能，都能有效的降低开关电源系统的待机功耗，提高功率转换效率。

内置的同步斜波补偿、反馈引脚的前沿消隐等功能不仅能减少开关电源系统的元器件数目，还增加了系统的稳定性，避免谐波振荡的产生。

QX5248还提供了多种全面的可恢复保护模式，保证了整体电源方案的稳定性。

应用l笔记本等电源适配器；l机顶盒电源；l开关电源；l电池充电器l LED射灯，球泡灯电源l LED日光灯电源特点l脉冲模式（Burst Mode）功能；l低启动电流(2uA)和低工作电流(1.6mA)；l内置前沿消隐；l内置同步斜坡补偿；l电流模式工作；l频率抖动技术，减小EMI；l外部可编程的PWM开关频率；l逐周期限流保护(OCP)；l内建系统VDD嵌位保护；l低电压关闭功能(UVLO)；l栅级驱动输出电压钳位(18V)；l恒定输出功率限制；l过载保护(OLP)；l工作时不产生音频噪声封装形式SOT23-6高性能电流模式PWM开关电源控制器内部框图封装脚位图引脚定义引脚符号引脚类型功能说明1 GND 电源电源地。

2 FB 反馈输入反馈输入引脚。

其输入电平值与6脚的电流侦测引脚共同确定PWM控制信号的占空比。

如果FB端的输入电压大于某个设定的阈值电压，则内部的保护电路会自动关断PWM输出。

3 RI 参考设置内部振荡频率设定引脚。

RI和GND之间所接的电阻决定芯片的工作频率。

4 SENSE 电流侦测电流检测反馈输入引脚。

连接到MOSFET电流检测电阻端。

5 VDD 电源电源。

6 GATE 驱动输出图腾柱栅极驱动输出引脚。

用于驱动外接的MOSFET 开关管。

CR5228规格书-中文版,欢迎观看,下载

斜波补偿电路在 SENSE 端检测电压信号上叠加了一个三角波信号。这极大的改善了系统工作在 CCM 模式的闭环稳定性，防止次谐波振荡，减小输出纹波电压。
功率管驱动
CR5228 内置功率 MOSFET 采用栅极软驱动控制。栅极驱动能力太弱将导致较高的开关损耗；栅极驱动能力太强又将导致 EMI 特性较差。因此两者之间必须采取一定的折中设计。
VDD 欠压锁定保护（UVLO）、过压保护（OVP）及箝位、逐周期电流限制（OCP）、过载保护（OLP）和图腾柱输出驱动高箝位等，特别对音频噪声和 FM 干扰进行了处理。芯片内置的频率抖动和图腾柱栅极软驱动技术可容易地获得良好的 EMI 性能。

工作描述
启动电流和启动控制
CR5228 具有很低的启动电流，实际应用时可以采用一个非常大的启动电阻，既能满足芯片的快速启动，又能使启动功率损耗减到最小。例如，对于全输入电压范围的 AC/DC 转换器应用，只需要一个 2MΩ、0.125W 的电阻与 VDD 外面的小电容相连就能使芯片快速启动。

NOTES: (1) The Zener Impedance is derived from the 1kHz AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (IZT or IZK) is superimposed on IZT or IZK. Zener Impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. (2) Measured with device junction in thermal equilibrium.
