If the output switch is driven into hard saturation (non Darlington configuration) at low switch currents (< 300 mA) andhigh driver currents (>30 mA), it may take up to 2.0 µs to come out of saturation This condition will shorten the off' timeat frequencies > 30 kHz, and is magnified at high temperatures This condition does not occur with a Darlington configuration,since the output switch cannot saturate If a non Darlington configuration is used, the following output drive condition isrecommendedForced β of output switch = I C , output/(Ic, driver -7.0 mA*) > 10*The 100 Ω. resistor in the emitter of the driver device requires about 7.0 mA before the output switch conducts**Possible version for shipmentPin connection。

Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible2. If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents (<=300mA)and high driver currents (>=30mA), it may take up to 2uS for it to come out of saturation. This condition will shorten the off time at frequencies >= 30KHz, and is magnified at high temperature. This condition does not occur with a Darlington configuration, since the output switch cannot saturate. If a non-Darlington configuration is used, the following output drive condition is recommended:Forced Bata of output switch: Ic output / (Ic driver – 7mA*) >= 10* The 100ohm resistor in the emitter of the driver divide requires about 7mA before the output switch conducts.Circuit DescriptionTypical Application CircuitFigure 7.

电路原理
内部框图中所表示的电路解释如下：振荡器通过恒流源对外接在 CT 管脚(3 脚)上的定时电容不断地充电和放电，以产生振荡波形。充电和放电电流都是恒定的，所以振荡频率仅取决于外接定时电容的容量。与门的 C 输入端在振荡器对外充电时为高电平，D 输入端在比较器的输入电平低于阈值电平时为高电平。当 C 和 D 输入端都变成高电平时，触发器被置为高电平，输出开关管导通。反之，当振荡器在放电期间，C 输入端为低电平，触发器被复位，使得输出开关管处于关闭状态。限制 SI 检测端(5 脚)通过检测连接在 V+和 5 脚之间电阻上的压降来完成功能。当检测到电阻上的电压降接近超过 300mV 时，电流限制电路开始工作。这时通过 CT 管脚(3 脚)对定时电容进行快速充电，以减少充电时间和输出开关管的导通时间，结果是使得输出开关管的关闭时间延长。

外围元件标称含义和它们取值的计算公式：Vout(输出电压)＝1.25V（１＋R1／R2 ）Ct( 定时电容)：决定内部工作频率。

Ct=0.000 004*Ton(工作频率）Ipk=2*Iomax*T/toffRsc( 限流电阻)：决定输出电流。

Rsc＝0.33／IpkLmin (电感)：Lmin＝(Vimin－Vces)*Ton/ IpkCo(滤波电容)：决定输出电压波纹系数，Co＝Io*ton/Vp-p(波纹系数）固定值参数：ton/toff=(Vo+Vf－Vimin)/(Vimin－Vces）Vces=1.0VVimin:输入电压范围的最小值Vf=1.2V 快速开关二极管正向压降在实际应用中的注意：快速开关二极管可以选用IN4148，在要求高效率的场合必须使用IN5819(贴片为SS14)；2、34063能承受的电压，即输入输出电压绝对值之和不能超过40V，否则不能安全稳定的工作；3、输出功率达不到要求的时候，比如＞1A时，可以通过外接扩功率管的方法扩大输出电流，三极管、双极型或MOS管均可，一般的芯片PDF资料上都会有典型扩流电路介绍；MC34063的扩展输出电流的应用DC/DC 转换器 34063 开关管允许的峰值电流为 1.5A，超过这个值可能会造成34063 永久损坏。

由于通过开关管的电流为梯形波，所以输出的平均电流和峰值电流间存在一个差值。

如果使用较大的电感，这个差值就会比较小，这样输出的平均电流就可以做得比较大。

例如，输入电压为9V，输出电压为3.3V，采用220 μH 的电感，输出平均电流达到 900mA，峰值电流为 1200mA。

单纯依赖34063 内部的开关管实现比900mA 更高的输出电流不是不可以做到，但可靠性会受影响。

Note 3: Low duty cycle pulse technique are used during test to maintain junction temperature as close to ambient temperature as possible.Note 4: If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents (d 300mA) and high driver currents (t 30mA), it may take up to 2.0us for it to come out of saturation. This condition will shorten the off time at frequencies 30KHz, and is magnified at high temperatures.

Step-Up Converter (Note 5)Note 5: This is a typical step-up converter configuration. In the steady state, if the resistor divider voltage at pin5 is greater than the voltage in the non-inverting input, which is 1.25V determined by the internal reference, the output of the comparator will go low. At the next swithching period, the output switch will not conduct and the output voltage will eventually drop below its nominal voltage until the divider voltage at pin 5 is lower than 1.25V.Then the output of the comparator will go high, the output switch will be allowed to conduct. Since Vpin5 = V OUT * R2/(R1+R2) = 1.25(V), the output voltage can be decided by V OUT = 1.25 * (R1+R2)/R2 (V).Apr. 2005 Rev. 1. 281.5A STEP-DOWN/STEP-UP/INVERTING DC-DC CONVERTER AZ34063A Typical Applications (Continued)Figure 11. Step-Down converter (Note 6)Note 6: This is a typical step-down converter configuration. The working process in the steady state is similar to step-up converter, Vpin5 = V OUT * R2/(R1+R2) = 1.25 (V), the output voltage can be decided by V OUT = 1.25 * (R1+R2)/R2 (V).Apr. 2005 Rev. 1. 291.5A STEP-DOWN/STEP-UP/INVERTING DC-DC CONVERTER AZ34063A Typical Applications (Continued)Figure 12. Voltage Inverting Converter (Note 7)Note 7: This is a typical inverting converter configuration. The working process in the steady state is similar to step-upconverter, the difference in this situation is that the voltage at the non-inverting pin of the comparator is equal to 1.25V+V OUT, then Vpin5 = V OUT * R2/(R1+R2) = 1.25V+V OUT, so the output voltage can be decided by V OUT = -1.25 * (R1+R2)/R1 (V).Apr. 2005 Rev. 1. 2101.5A STEP-DOWN/STEP-UP/INVERTING DC-DC CONVERTER AZ34063A Mechanical DimensionsSOIC-8Unit: mm(inch)Apr. 2005 Rev. 1. 2111.5A STEP-DOWN/STEP-UP/INVERTING DC-DC CONVERTER AZ34063A Mechanical Dimensions (continued)DIP-8Unit: mm(inch)Apr. 2005 Rev. 1. 212/doc/23f0a013a8114431b80dd800.ht mlBCD Semiconductor Corporation3170 De La Cruz Blvd, Suite # 105 Santa Clara, CA 95054-2411, U.S.A Tel: +1-408-988 6388, Fax: +1-408-988 6386 Shanghai SIM-BCD Semiconductor Manufacturing Co., Ltd.800 Yi Shan Road, Shanghai 200233, PRC Tel: +86-21-6485-1491, Fax: +86-21-5450-0008 Advanced Analog Circuits (Shanghai) Corporation8F, B Zone, 900 Yi Shan Road, Shanghai 200233, PRC Tel: +86-21-6495 9539, Fax: +86-21-6485 9673 BCD Semiconductor(Taiwan) Company LimitedRoom 2210, 22nd Fl, 333, Keelung Road, Sec. 1, TaiPei (110), Taiwan Tel: +886-2-2758 6828, Fax: +886-2-2758 6892 IMPORTANT NOTICEBCD Semiconductor Manufacturing Limited reserves the right to make changes without further notice to any pro-ducts or specifications herein.
