间接代换P1014AP10的两种方法
作者：郑秀峰
来源：《卫星电视与宽带多媒体》2012年第06期
间接代换P1014AP10的两种方法
NCP1014是美国安森美半导体公司（ON Semiconductor）研制的电源管理芯片，同系列
的还有NCP1010、NCP1011、NCP1012、NCP1013，在外星人、地球人、诺普斯、Glomax等品牌数字机的开关电源中采用NCP1014。
如NCP1014损坏后可用同系列或TYN264P-268P直接代换，如无元件供直接代换，可考虑用外围电路简捷的其他电源管理芯片间接代换，当然要对原电路进行稍加改动，需改动的电路部分越少越好，有时有可能还需要增加几个元件。
图1、图2分别为用VIPer22A、TOP224Y间接代换NCP1014电路原理图，是在Glomax 5066型数字卫星接收机原开关电源的基础上进行的，“×”处为切断的电路处，虚线为修改的连接线。
代换时，先将损坏的P1014AP10拆下，按照VIPer22A或TOP224Y应用电路改动，重新连线即可。
代换时应注意原电路中其他元件是否有损坏的情况，否则代换后也不能正常工作。
用TOP224Y代换时，需在控制端（C）和源极（S）间增加一个电阻R（10-47Ω）、一个电解电容C（47-220μF/16V），还应根据TOP224Y芯片温升情况决定是否加装散热片。

Designed to reduce logic supply current, chip size, and system cost, the UCN5833A/EP integrated circuits offer high-speed operation for thermal printers. These devices can also be used to drive multi-plexed LED displays or incandescent lamps within their 125 mA peak output current rating. The combination of bipolar and MOS technolo-gies gives BiMOS II smart power ICs an interface flexibility beyond the reach of standard buffers and power driver circuits.These 32-bit drivers have bipolar open-collector npn Darlington outputs, a CMOS data latch for each of the drivers, a 32-bit CMOS shift register, and CMOS control circuitry. The high-speed CMOS shift registers and latches allow operation with most microprocessor-based systems at data input rates above 3.3 MHz. Use of these drivers with TTL may require input pull-up resistors to ensure an input logic high.The UCN5833A is supplied in a 40-pin dual in-line plastic package with 0.600" (15.24 mm) row spacing. At an ambient temperature of +75°C, all outputs of the DlP-packaged device will sustain 50 mA continuously. For high-density applications, the UCN5833EP is available.

描述M5832应用于小功率AC/DC充电器和电源适配器的高性能离线式脉宽调制控制器。
该芯片是一款基于原边检测和调整的控制器，因此在应用时无需TL431和光耦。
芯片内置了恒流/恒压两种控制方式，其典型的控制曲线如图1所示。
在恒流控制时，恒流值和输出功率可以通过SEN 引脚的限流电阻RS设定。
在恒压控制时，芯片在INV脚采样辅助绕组的电压，进而调整输出。
在恒压控制时还采用了多种模式的控制方式，这样既保证了芯片的高性能和高精度，又保证了高效率。
此外，通过内置的线损补偿电路保证了较高的输出电压精度。
典型应用图特征⇒恒压和恒流精度可达5%⇒原边控制模式，无需TL431和光耦⇒非连续模式下的反激拓扑⇒准谐振开关模式，减小开关损耗⇒具有软启动功能典型应用图极限参数脚位示意图限值，不建议器件工作在推荐条件以外的情况。
器件长时间工作在极限工作条件下，其可靠性及寿命可能受到影响。
芯片框图应用信息描述M5832是一款低成本、高性价比的脉宽调制控制器，适用于离线式小功率AC/DC电池充电器和电源适配器。
它采用原边控制方式，因此不需要TL431和光耦。
M5832应用于工作在非连续模式下的反激式系统中，内置的次图2级恒压采样电路能够提供高精度恒流/恒压控制，很好地满足大多数电源适配器和充电器的要求。
启动M5832供电电源端是VDD 。
启动电阻提供了从高压端到VDD 旁路电容的直流通路，为芯片提供启动电流。
M5832的启动电流小于20uA ，因此VDD 能够很快被充到UVLO （off ）以上，从而使芯片快速启动并开始工作。
采用较大的启动电阻可以减小整机的待机功耗。
一旦VDD 超过UVLO （off ），芯片就进入软启动状态，使M5832的峰值电流电压逐渐从0V 增加到0.9V ，用以减轻在启动时对电路元件的冲击。
VDD 的旁路电容一直为芯片提供供电直到输出电压足够高以至于能够支撑VDD 通过辅助绕组供电为止。

Step-up voltage converters coupled with level shifting transmitters and receivers allow RS-232 levels to be developed while operating from a single +3.3 V supply.CMOS technology is used to keep the power dissipation to an absolute minimum, allowing maximum battery life in portable applications.The ADM3202/ADM3222/ADM1385 is a modification, en-hancement and improvement to the AD230–AD241 family and its derivatives. It is essentially plug-in compatible and does not have materially different applications.CIRCUIT DESCRIPTIONThe internal circuitry consists of three main sections. These are:1.A charge pump voltage converter2.3.3V logic to EIA-232 transmitters3.EIA-232 to 5V logic receivers.Charge Pump DC-DC Voltage ConverterThe charge pump voltage converter consists of a 200 kHz oscil-lator and a switching matrix. The converter generates a ±6.6V supply from the input +3.3 V level. This is done in two stages using a switched capacitor technique as illustrated below. First, the +3.3V input supply is doubled to +6.6 V using capacitorC1 as the charge storage element. The +6.6V level is then inverted to generate –6.6 V using C2 as the storage element. C3 is shown connected between V+ and V CC, but is equally effec-tive if connected between V+ and GND.Capacitors C3 and C4 are used to reduce the output ripple. Their values are not critical and can be increased if desired. Capacitor C3 is shown connected between V+ and V CC. It is also acceptable to connect this capacitor between V+ and GND. If desired, larger capacitors (up to 10 µF) can be used for capacitors C1–C4.Figure 8.Typical Operating Circuits Figure 7.230 kbps Data TransmissionADM3202/ADM3222/ADM1385OUTLINE DIMENSIONSDimensions shown in inches and (mm).16-Lead Plastic DIP(N-16)16-Lead Thin Shrink Small Outline (TSSOP)(RU-16)PLANE BSC0.0035 (0.090)16-Lead Narrow Body SOIC(R-16A)؇16-Lead Wide Body SOIC(R-16)Figure 9.Charge Pump Voltage DoublerFigure 10.Charge Pump Voltage InverterTransmitter (Driver) SectionThe drivers convert 3.3V logic input levels into RS-232 output levels. With V CC = +3.3V and driving an RS-232 load, the output voltage swing is typically ±6 V.Receiver SectionThe receivers are inverting level-shifters that accept RS-232input levels and translate them into 3 V logic output levels.The inputs have internal 5 k Ω pull-down resistors to ground and are also protected against overvoltages of up to ±30 V. Uncon-nected inputs are pulled to 0 V by the internal 5 k Ω pull-down resistor. This, therefore, results in a Logic 1 output level for unconnected inputs or for inputs connected to GND.The receivers have Schmitt trigger inputs with a hysteresis level of 0.4 V. This ensures error-free reception for both noisy inputs and for inputs with slow transition times.HIGH BAUD RATEThe ADM3202E/ADM3222E feature high slew rates permitting data transmission at rates well in excess of the EIA/RS-232E specifications. RS-232 voltage levels are maintained at data rates up to 460 kbps even under worst case loading conditions. This allows for high speed data links between two terminals or indeed it is suitable for the new generation I SDN modem standards which requires data rates of 230 kbps. The slew rate is internally con-trolled to less than 30 V/µs in order to minimize EMI interference.ADM3202/ADM3222/ADM1385C 00071–0–8/00 (r e v .

应用信息
●描述
M5832是一款低成本、高性价比的脉宽调制控制器，适用于离线式小功率AC/DC电池充电器和电源适配器。
它采用原边控制方式，因此不需要TL431和光耦。
M5832应用于工作在非连续模式下的反激式系统中，内置的次级恒压采样电路能够提供高精度恒流/恒压控制，很好地满足大多数电源适配器和充电器的要求。
●启动
M5832供电电源端是VDD。
启动电阻提供了从高压端到VDD旁路电容的直流通路，为芯片提供启动电流。
M5832的启动电流小于20uA，因此VDD能够很快被充到UVLO（off）以上，从而使芯片快速启动并开始工作。
采用较大的启动电阻可以减小整机的待机功耗。
一旦VDD超过UVLO（off），芯片就进入软启动状态，使M5832的峰值电流电压逐渐从0V增加到0.9V，用以减轻
在启动时对电路元件的冲击。
VDD的旁路电容一直为芯片提供供
电直到输出电压足够高以至于能够支撑VDD通过辅助绕组供电
为止。
●恒流工作
M5832的恒压
/恒流特征曲线如图1所示。
M5832被设计应用于工作在非连续模式下的反激式系统中。
在正常工作时，当INV 电压低于内部2.0V 的基准电压好时，系统工作在恒流模式，否则系统工作在恒压模式。
当次级输出电流达到了系统设定的最大电流时，系统就进入恒流模式，并且会引起输出电压的下降。
随着输出电压的下降，反馈电压也跟着下降，芯片内部的VCO 将会调整开关的频率，以使输出功率保持和输出电压成正比，其结果就是使输出电流保持恒定。
这就是恒流的原理。
在恒流模式下，无论输出电压如何变化，输出电流为一常数。
在作为充电器应用时，先是恒流充电直到接近电池充饱的状态，随后再进行恒压充电。
在M5832中,恒流值和最大输出功率可以通过外部的限流电阻RS 来设定。
输出功率的大小随着恒流值的变化而变化。
RS 越大，恒流值就越小，输出功率也越小；RS 越小，恒流值就越大，输出功率也越大。
具体参照图2所示。
● 恒压工作
在恒压控制时，M5832利用辅助绕组通过电阻分压器从INV 采样输出电压，并将采样的输出电压与芯片内部的基准电压通过误差放大器进行比较放大，从而调整输出电压。
当采样电压高于内部基准电压，误差放大器的输出电压COM 减小，从而减小开关占空比；当采样电压低于内部基准电压时，误差放大器的输出电压COM 增加，从而增大开关占空比，通过这种方式稳定输出电压。
在作为AC/DC 电源应用时，正常工作时芯片处于恒压状态。
在恒压模式下，系统输出电压通过原边进行控制。
为了实现M5832的恒流/恒压控制，系统必须工作在反激式系统的非连续模式。
（参照典型应用电路）在非连续模式的反激式转换器中，输出电压能够通过辅助绕组来设定。
当功率MOSFET 导通时，负载电流由输出滤波电容CO 提供，原边电流呈斜坡上升，系统将能量存储在变压器的磁芯中，当功率MOSFET 关断时，存储在变压器磁芯中的能量传递到输出。
此时辅助绕组反射输出电压，具体如图3所示，计算公式如下：
其中∆V 是指整流二极管上的压降
通过一个电阻分压器连接到辅助绕组和INV 之间，这样，通过芯片内部的控制算法，辅助组上的电压在去磁结束时被采样并保持，直至下一次采样。
采样到的电压和内部2.0V 的基准电压比较，将其误差放大。
误差放大器的输出COM 反映负载的状况，控制脉宽调制开关的占空比，进而调整输出电压，这样就实现了恒压控制 ● 线损补偿
随着负载电流的增加，导线上的电压降也会增加，导致输出电压的减小。
M5832内置的线损补偿电路能够补偿导线的损耗压降，从而稳定输出电压。
当引入了导线损耗压降以后，辅
图2
助绕组反射输出电压的计算公式（1）将会被修正为。
其中Vcable为导线上的损耗压降。
为了补偿导线上的损耗压降，一个电压偏移量被叠加到INV上。
这个电压偏移量是由一个内部电流IC流入电阻分压器产生的，具体的控制电路如图4所示。
线损补偿电流IC与误差放大器的输出COM成反比，因此，也与输出负载电流成反比。
基于以上原理，线损补偿得以实现，具体的计算公式如下:
当系统从满载变到空载的过程中，叠加到INV的电压偏移量将会增加。
在应用时可以通过调节电阻分压器中电阻的大小来调整补偿的多少。
在恒压模式下，引入线损补偿提高了输出电压的精度和负载调整率。
●开关工作频率
M5832的开关频率受控于负载状况和工作模式。
内部电路设定最大开关频率为60KHz。
在反激模式的断续工作时，最大输出功率通过以下公式计算：
其中LP是变压器原边电感值，IP是原边峰值电流。
为了系统能够安全的工作，原边采样电路必须工作在非连续模式。
为了防止系统进入连续工作模式，开关频率被内部环路锁定，此时的开关频率为：
由于TDemag与电感的大小成反比，因此，电感LP和FSW的乘积为一定值，从而限制了最大的输出功率，避免了系统进入连续工作模式。
●电流检测和前沿消隐
M5832采样功率MOSFET上的电流是通过SEN来实现的。
M5832不仅设计了逐周期的电流限制，而且设计了峰值电流限制，最大的峰值电流电压为0.9V。
因此，MOSFET上最大的峰值电流为:
M5832在SEN端设计了一个约为540ns的前沿消隐时间用来防止在开关导通时刻错误的过流保护被触发。
因此，不需要在SEN端在增加额外的RC滤波电路。
采样电流的输入信号SEN和误差放大器的输出COM 共同决定开关的占空比，稳定输出.
●EMI特性的改善
为了改善M5832系统的EMI特性，芯片内部采用了两种方式。
其中一种方式是采用频率抖动，即在M5832正常工作频率的基础上叠加一个微小的扰动。
也就是说，内部振荡器的频率被调制用来分散谐波干扰能量，分散的能量能够最小化EMI带宽。
另一种方式是软驱动，即逐渐打开功率MOSFET。
当提供给功率MOSFET
的栅驱动太强时，EMI特性会变差；当提供给功率MOSFET的栅驱动太弱时，开关损耗又会加大，因此需要在EMI特性和开关损耗之间寻求折衷来提供合适的栅驱动。
M5832采用了软驱动和图腾柱输出结构，既获得了很好的EMI特性，又降低了开关损耗。
频率抖动和软驱动的综合应用使系统的EMI特性获得了很大的改善。
保护控制
M5832为了确保系统的正常工作内置了多重保护措施。
当这些保护措施一旦被触发，将会关断MOSFET。
这些保护措施包括逐周期的电流限制、峰值电流限制、过温保护、电源箝位、软启动、欠压锁定等。
芯片的供电电源VDD由辅助绕组提供。
当VDD低于进入欠压锁定的阈值电压时，开关将会被关断，随后系统自动进入重启状态。
M5832每次的重启都具有软启动功能。
