脉宽调制器 脉宽调制器通过驱动输出MOSFET来实现多模式控制，其占空比与流入控制脚超过芯片内部消 耗所需要的电流成反比（如图3）。反馈误差信号以过电流的形式， 由一个典型转折频率为 7 kHz的RC滤波电路进行滤波，以降低芯片电源电流中由MOSFET栅极驱动产生的开关噪音。 要优化电源效率，需要实施四个不同的控制模式。在最大负载条件下，调制器将在全频PWM 模式下进行工作，随着负载的增加，调制器将自动依次切换到变频PWM模式和低频PWM模式。 在轻负载条件下，控制方式将从PWM控制切换到多周期调制控制，调制器在多周期调制模式 下进行工作。虽然不同模式的工作方式有所不同，但为了实现模式间的平滑切换，图3中所
振荡器和开关频率 内部振荡器使内部电容在两个设定的电压值间线性充放电，以产生脉宽调制解调器所需的三 角波电压。在每个周期的起点，振荡器将脉宽调制解调器/电流限制的触发器电路置位。全 开关频率选择为66kHz。全频PWM模式下，66kHz开关频率大约在±2.5kHz的范围内以250Hz 的速率抖动。当系统进入固定漏极峰值电流的变频模式后，频率抖动将关闭。

Descriptions:1. Delta will not guarantee the performance of the products if the application condition fallsoutside the parameters set forth in the specification.2. A written request should be submitted to Delta prior to approval if deviation from thisspecification is required.3. Please exercise caution when handling fans. Damage may be caused when pressure is appliedto the impeller, if the fans are handled by the lead wires, or if the fans are hard-dropped to the production floor.4. Except as pertains to some special designs, there is no guarantee that the products will be freefrom any such safety problems or failures as caused by the introduction of powder, droplets of water or encroachment of insect into the hub.5. The above-mentioned conditions are representative of some unique examples and viewed as thefirst point of reference prior to all other information.6. It is very important to establish the correct polarity before connecting the fan to the powersource. Positive (+) and Negative (-). Damage may be caused to the fans if connection is with reverse polarity, as there is no foolproof method to protect against such error.7. Delta fans are not suitable where any corrosive fluids are introduced to their environment.8. Please ensure all fans are stored according to the storage temperature limits specified. Do notstore fans in a high humidity environment. We highly recommend performance testing is conducted before shipping, if the fans have been stored over 6 months.9. Not all fans are provided with the Lock Rotor Protection feature. If you impair the rotation ofthe impeller for the fans that do not have this function, the performance of those fans will lead to failure.10. Please be cautious when mounting the fan. Incorrect mounting of fans may cause excessresonance, vibration and subsequent noise.11. It is important to consider safety when testing the fans. A suitable fan guard should be fitted tothe fan to guard against any potential for personal injury.12. Except where specifically stated, all tests are carried out at relative (ambient) temperature andhumidity conditions of 25o C, 65%. The test value is only for fan performance itself.13. Be certain to connect an “over 4.7µF” capacitor to the fan externally when the application callsfor using multiple fans in parallel, to avoid any unstable power.分销商库存信息: DELTA-PRODUCT-GROUPS AFB1212HHE。
