开关电源uc2844中文资料详细（uc2844引脚功能应用电子电路发表于 2018-01-02 09:15:50开关电源uc2844采用双列直插8脚封装;电流脉冲宽度调制器，输入电压范围5～30V，最大功耗=1W，振荡器频率≥500kHz，基准电压=5V，电压调整率=6mV，电流调整率=6mA，输出端最大电流=1000mA，最大占空度=95%。
内含振荡器、高增益误差放大、锁存器、推挽输出电路等，具有过压、过流检测保护功能。
uc2844引脚功能uc2844工作原理电源电路采用了电流PWM控制模式，就使反激式电路形成了稳定性很好的双环路反馈（输出直流电压隔离取样反馈外回路和初级线圈充磁峰值电流取样反馈内回路）控制系统，就可以通过开关电源的PWM调制器迅速调整脉冲占空比，从而在每一个周期内对前一个周期的输出电压和初级线圈充磁峰值电流进行有效调节，达到稳定输出电压的目的。
这种反馈控制电路的最大特点是：在输入电压和负载电流变化较大时，具有更快的动态响应速度，自动限制负载电流，补偿电路简单。
反激电路适应于小功率开关电源。
单端反激式开关电源是以开关管的周期性导通与截止为主要特征。
开关导通时，在变压器的原边线圈一侧储存电能，与副边线圈相连的超快恢复二极管处于反偏压状态，所以二极管截止，在变压器次级线圈中无电流流过，即没有能量传递给负载。
开关管截止时，变压器副边电感线圈中的电压极性反转，使二极管导通，给输出电容充电，同时负载也有电流流过。
uc2844应用电路下图是为变频器设计的反激式开关电源的典型电路，主要包括交流输入整流电路，反激式开关电源功率级电路（有PWM控制器、MOS管、变压器及整流二极管组成），RCD缓冲电路和反馈网络。
其中PWM控制芯片采用UC2844。
UC2844是电流模式控制器，芯片内部具有可微调的振荡器（能进行精确的占空比控制）、温度补偿的参考基准、高增益误差放大器、电流取样比较器。
反激式开关电源典型设计。

Ultra Low ON-Resistance, Low Voltage, Single Supply, Dual SPDT Analog Switch
The Intersil ISL84684 device is a low ON-resistance, low voltage, bidirectional, dual single-pole/double-throw (SPDT) analog switch designed to operate from a single +1.65V to +3.6V supply. Targeted applications include battery powered equipment that benefit from low RON (0.25Ω) and fast switching speeds (tON = 14ns, tOFF = 6ns). The digital logic input is 1.8V logic-compatible when using a single +3V supply.

The UC384xA family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include a trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lockout featuring start-up current less than 0.5mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control, and a totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N-Channel MOSFETs, is low in the off-state.

*Please refer to TB347 for details on reel specifications. NOTES:
The parts draw minimal supply current (900µA per amplifier) while meeting excellent DC accuracy, AC performance, noise and output drive specifications. The ISL28148 features an enable pin that can be used to turn the device off and reduce the supply current to a maximum of 16µA. Operation is guaranteed over -40°C to +125°C temperature range.
