获得性长QT间期综合征的防治建议
・９６４・ＴｄＰ发作的心电图预警参数某腾心电图改变可以作为预警信号提示ＴｄＰ的发生。
应注意这些典型的心电图预警表现往往呈动态变化。
同一患者不同时间的心电图变化不同，尤其是Ｔ－ｕ波的畸形，往往随着心动周期的变化而变化，需要动态监测才能发现。
Ｉ．ＱＴｃ间期延长：在先天性ＬＱｌｓ患者中，ＱＴｃ每增加１０咖使ＴｄＰ的发生危险呈５％一７％指数性的增加旧彤１。
啦＞５００Ｉｌｌｓ者ＴｄＰ的发生危险增加２～３倍。
药物诱发帆＞５００ｒｎ￥时，ＴｄＰ的危险也同样增加¨…。
但目前没有一个明确的可诱发ＴｄＰ的ＱＴｃ阈值。
尽管对于先天性ＬＱＴｓ的研究显示，发生晕厥和猝死的危险与ＱＴ间期长短有直接的关系惮Ｊ，但只靠监测ＱＴ／ＱＴｃ间期来预测ＴｄＰ是不够的惭Ｊ，还需注意下述其他心电图改变。
２．Ｔ－Ｕ波畸形和间歇依赖现象：Ｔ・ｕ波形态异常通常包括Ｔ波低平、双向、ｕ波加大并与Ｔ波融合、Ｔ波降支逐渐下降并时限延长，使Ｔ波的末端难以辨认。
一些报道指出，Ｔ波波峰至Ｔ波终末（Ｔｐ—Ｔｅ）时程代表着整个心脏最早和最迟复极完毕的时间问期。
Ｔｐ－Ｔｅ延长是心肌复极离散度增加的表现，容易发生ＴｄＰ惭。
Ｊ。
药物诱发的ＬＱ，ｒｓ患者，在正常窦性心律时可能没有不良效应。
但在ＴｃｌＰ开始前可出现典型的短一长－短ＲＲ问期（间歇依赖现象），即长间歇后心搏的ＱＴ间期明显延长，Ｔ．ｕ波形态也明显异常。
电生理研究表明，间歇后心搏的异常Ｔ—Ｕ波的振幅与间歇的长度和间歇前的心率有关嘲Ｊ。
出现长间歇的原因最可能是早搏的代偿问期，暂时性的窦性停搏或房室传导阻滞，但也可能是变化十分微小的窦性心律不齐。
这种不同心搏之间的ＱＴ间期不稳定性与心律失常发生的机制有关旧Ｊ。
由此而产生的显著ＱＴ问期延长和Ｔ．ｕ波形态异常可以触发窜早，从而再次产生长间歇，直至ＴｄＰ的发生。
因此心脏间歇后出现显著的ＱＴ间期延长和Ｔ．Ｕ波形态异常应当认为是发生ＴｄＰ的强预警信号。
这种间歇依赖现象虽可在１２导联心电图中记录到，但更常见于监测心电图（图Ｉ）。

The feedbackthreshold voltage is 0.6V.MP2105 – 1MHz 800mA SYNCHRONOUS STEP-DOWN CONVERTERTMOPERATIONThe MP2105 is a constant frequency current mode PWM step-down converter. The MP2105 is optimized for low voltage, Li-Ion battery powered applications where high efficiency and small size are critical. The MP2105 uses an external resistor divider to set the output voltage from 0.6V to 6V. The device integrates both a main switch and a synchronous rectifier, which provides high efficiency and eliminatesan external Schottky diode. The MP2105 can achieve 100% duty cycle. The duty cycle D of a step-down converter is defined as:%100V V %100f T D INOUTOSC ON ×≈××= where T ON is the main switch on time, and f OSC is the oscillator frequency (1MHz).INENFBGNDSWMP2105_BD01Figure 1—Functional Block DiagramMP2105 – 1MHz 800mA SYNCHRONOUS STEP-DOWN CONVERTERTMCurrent Mode PWM ControlSlope compensated current mode PWM control provides stable switching and cycle-by-cycle current limit for superior load and line response and protection of the internal main switch and synchronous rectifier. The MP2105 switches at a constant frequency (1MHz) and regulates the output voltage. During each cycle the PWM comparator modulates the power transferred to the load by changing the inductor peak current based on the feedback error voltage. During normal operation, the main switch is turned on for a certain time to ramp the inductor current at each rising edge of the internal oscillator, and switched off when the peak inductor current is above the error voltage. When the main switch is off, the synchronous rectifier will be turned on immediately and stay on until either the next cycle starts. Dropout OperationThe MP2105 allows the main switch to remain on for more than one switching cycle and increases the duty cycle while the input voltage is dropping close to the output voltage. When the duty cycle reaches 100%, the main switch is held on continuously to deliver current to the output up tothe PFET current limit. The output voltage then is the input voltage minus the voltage drop across the main switch and the inductor.Short Circuit ProtectionThe MP2105 has short circuit protection. When the output is shorted to ground, the oscillator frequency is reduced to prevent the inductor current from increasing beyond the PFET current limit. The PFET current limit is also reduced to lower the short circuit current. The frequency and current limit will return to the normal values once the short circuit condition is removed and the feedback voltage reaches 0.6V.Maximum Load CurrentThe MP2105 can operate down to 2.5V input voltage; however the maximum load current decreases at lower input due to large IR drop on the main switch and synchronous rectifier. The slope compensation signal reduces the peak inductor current as a function of the duty cycle to prevent sub-harmonic oscillations at duty cycles greater than 50%. Conversely the current limit increases as the duty cycle decreases.APPLICATION INFORMATIONOutput Voltage SettingThe external resistor divider sets the output voltage (see Figure 3). The feedback resistor R1 also sets the feedback loop bandwidth with the internal compensation capacitor (see Figure 1). Choose R1 around 500k Ω for optimal transient response. R2 is then given by:1V6.0V 1R 2R OUT−=Table 1—Resistor Selection vs. OutputVoltage SettingV OUT R1 R2 1.2V 499k Ω (1%) 499k Ω (1%) 1.5V 499k Ω (1%) 332k Ω (1%) 1.8V 499k Ω (1%) 249k Ω (1%) 2.5V499k Ω (1%)158k Ω (1%)Inductor SelectionA 1µH to 10µH inductor with DC current rating at least 25% higher than the maximum load current is recommended for most applications. For best efficiency, the inductor DC resistance shall be <200m Ω. See Table 2 for recommended inductors and manufacturers. For most designs, the inductance value can be derived from the following equation:()OSCL IN OUT IN OUT f I V V V V L ×∆×−×=where ∆I L is Inductor Ripple Current. Choose inductor ripple current approximately 30% of the maximum load current, 800mA.The maximum inductor peak current is:2I I I LLOAD )MAX (L ∆+= Under light load conditions below 100mA, larger inductance is recommended for improved efficiency.

The input capacitor impedance at the switching frequency shall be less than input source impedance to prevent high frequency switching current passing to the input. Ceramic capacitors with X5R or X7R dielectrics are highly recommended because of their low ESR and small temperature coefficients. For most applications, a 4.7µF capacitor is sufficient. Output Capacitor SelectionThe output capacitor keeps output voltage ripple small and ensures regulation loop stable. The output capacitor impedance shall be low at the switching frequency. Ceramic capacitors with X5R or X7R dielectrics are recommended.

AP1512/A50KHz, 2A/3A PWM Buck DC/DC ConverterFeatures- Output voltage: 3.3V, 5V, 12V and adjustable output version- Adjustable version output voltage range, 1.23V to 37V+4%- 50KHz +15% fixed switching frequency- Voltage mode non-synchronous PWM control - Thermal-shutdown and current-limit protection - ON/OFF shutdown control input - Operating voltage can be up to 60V - Output load current: 2A (for AP1512)3A (for AP1512A)- Low power standby mode- Built-in switching transistor on chip - TO220-5L, TO220-5L(R) and TO263-5L Pb-free packagesApplications- Simple High-efficiency step-down regulator - On-card switching regulators - Positive to negative converterGeneral DescriptionThe AP1512/A is a monolithic IC that design for a step-down DC/DC converter, and own the ability of driving a 2A (3A for AP1512A) load without additional transistor component. Due to reducing the number of external component, the board space can be saved easily. The external shutdown function can be controlled by logic level and then come into standby mode. The internal compensation makes feedback control have good line and load regulation without external design. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch. The AP1512/A operates at a switching frequency of 50KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed +4% tolerance on output voltage under specified input voltage and output load conditions, and +15% on the oscillator frequency. The output version included fixed 3.3V, 5V, 12V, and an adjustable type. The packages are available in a standard 5-lead TO-220 package and a 5-lead TO-263.Pin AssignmentsTO220-5L( Top View )( Top View )TO263-5L INMetal Tab GNDINPin DescriptionsNameDescriptionV IN Operating voltage input Output Switching output Gnd Ground FBOutput voltage feedback controlSD ON/OFF ShutdownAP1512/A50KHz, 2A/3A PWM Buck DC/DC ConverterOrdering InformationPackage T5: TO220-5LK5: TO263-5LOutput Version AP1512 X XX X XPacking Blank : Tube A : TapingBlank : Adjustable -33 : 3.3V -50 : 5.0V -12 : 12VT5R: TO220-5L(R)Part Number Blank: 2A A : 3ABlock DiagramCurrent Source bias1.235V Reference2.5V Regulator50KHz OSC.Start up++_+_Thermal LimitPre-driverComp CompGndOutput V INSDFB220mV200mV2A Switch +__Amp CompFrequecy compen-sation(3A for AP1512A)AP1512/A50KHz, 2A/3A PWM Buck DC/DC ConverterAbsolute Maximum RatingsSymbol Parameter RatingUnit V CC Supply Voltage +63 V V SD ON/OFF Pin input voltage -0.3 to +40 V V FB Feedback Pin voltage -0.3 to +40V V OUT Output voltage to Ground -1V P D Power dissipation Internally limited W T ST Storage temperature -65 to +150 o C T OP Operating temperature -40 to +125 o C V OP Operating voltage+4.5 to +60VElectrical Characteristics (All Output Voltage Versions)Unless otherwise specified, V IN =30V for all version.

A suitable input bypass capacitor must be present at this pin to minimize voltage transients and to supply the switching currents needed by the regulator.GroundCircuit ground.OutputInternal switch. The voltage at this pin switches between (+V IN – V SAT ) and approximately – 0.5V, with a duty cycle of approximately V OUT / V IN . To minimize coupling to sensitive circuitry, the PC board copper area connected to this pin should be kept a minimum.FeedbackSenses the regulated output voltage to complete the feedback loop.ON /OFFAllows the switching regulator circuit to be shutdown using logic level signals thus dropping the total input supply current to approximately 150uA. Pulling this pin below a threshold voltage of approximately 1.3V turns the regulator on, and pulling this pin above 1.3V (up to a maximum of 40V) shuts the regulator down. If this shutdown feature is not needed, the SD pin can be wired to the ground pin or it can be left open, in either case the regulator will be in the ON condition.Thermal ConsiderationsThe AP1512/A is available in two packages, a 5-pin TO-220 and a 5-pin surface mount TO-263.The TO-220 package needs a heat sink under most conditions. The size of the heatsink depends on the input voltage, the output voltage, the load current and the ambient temperature. The AP1512/A junction temperature rises above ambient temperature for a 2A load and different input and output voltages. The data for these curves was taken with the AP1512/A (TO-220 package) operating as a buckswitching regulator in an ambient temperature of 25o C (still air). These temperature rise numbers are all approximate and there are many factors that can affect these temperatures. Higher ambient temperatures require more heat sinking.The TO-263 surface mount package tab is designed to be soldered to the copper on a printed circuit board. The copper and the board are the heat sink for this package and the other heat producing components, such as the catch diode and inductor. The PC board copper area that the package is soldered to should be at least 0.4 in 2, and ideally should have 2 or more square inches of 2 oz. Additional copper area improves the thermal characteristics, but with copper areas greater than approximately 6 in 2, only small improvements in heat dissipation are realized. If further thermal improvements are needed, double sided, multilayer PC board with large copper areas and/or airflow are recommended.AP1512/A50KHz, 2A/3A PWM Buck DC/DC ConverterFunction Description (Continued)The AP1512/A (TO-263 package) junction temperature rise above ambient temperature with a 2A load for various input and output voltages. This data was taken with the circuit operating as a buck switching regulator with all components mounted on a PC board to simulate the junction temperature under actual operating conditions. This curve can be used for a quick check for the approximate junction temperature for various conditions, but be aware that there are many factors that can affect the junction temperature. When load currents higher than 2A are used, double sided or multilayer PC boards with large copper areas and/or airflow might be needed, especially for high ambient temperatures and high output voltages.For the best thermal performance, wide copper traces and generous amounts of printed circuit board copper should be used in the board layout. (Once exception to this is the output (switch) pin, which should not have large areas of copper.) Large areas of copper provide the best transfer of heat (lower thermal resistance) to the surrounding air, and moving air lowers the thermal resistance even further.Package thermal resistance and junction temperature rise numbers are all approximate, and there are many factors that will affect these numbers. Some of these factors include board size, shape, thickness, position, location, and even board temperature. Other factors are, trace width, total printed circuit copper area, copper thickness, single or double-sided, multilayer board and the amount of solder on the board. The effectiveness of the PC board to dissipate heat also depends on the size, quantity and spacing of other components on the board, as well as whether the surrounding air is still or moving. Furthermore, some of these components such as the catch diode will add heat to the PC board and the heat can vary as the input voltage changes. For the inductor, depending on the physical size, type of core material and the DC resistance, it could either act as a heat sink taking heat away from the board, or it could add heat to the board.Marking Information(1) TO263-5L1512X-XX Blank: ADJ ( Top View )"02" = 2002"01" = 2001YY WW X01~52~Part Number:A: AP1512A(2) TO220-5L1512X-XX ID codeYear:"02" = 2002"01" = 2001YY WW XXth week:01~52~Blank: ADJ LogoPart Number:-Output Type: -33: 3.3V -50: 5.0V -12: 1.2V Blank: AP1512A: AP1512AAP1512/A 50KHz, 2A/3A PWM Buck DC/DC ConverterPackage Information(1) Package Type: TO220-5LD QEbe1AJ1FCΦPH1LeDimensions In Millimeters Dimensions In InchesSymbolMin.
