多功能、多种拓朴高频PWM控制器TPS43000

多功能、多种拓朴高频PWM控制器TPS43000

多功能、多种拓朴高频PWM控制器TPS43000TPS43000是一款高频电压型同步PWM控制器,它能用于BUCK、BOOST、SEPIC 或flyback拓朴的控制。

该款高度柔性,全新特色的控制器设计成可驱动一对外部功率MOSFET(一个为N沟,一个为P沟)的结构,因而具有很宽范围的输出电压和功率水平,还有自动的PFM模式工作,关断电流小于1μA,休息模式工作电流小于100μA,在1MHz时整个工作电流小于2mA,因而是一个高效率多用途的DC/DC控制器。

TPS43000输入电压范围从1.8V~9.0V,给分布式系统供电,可以由镍镉电池供电,也可以由锂电池供电,产生0.8V~8V的各输出电压(还可更高),用户可调节其PWM频率最高达2MHz,也可令其进入PFM模式,在此时若电感电流进入断续,则IC进入休息模式,在输出电压降下2%时再工作,在此工作模式,在很宽的负载电流时都有非常高的效率,器件还可以同步到外时钟频率。

TPS43000可选择两个水平的限流电路,它检测主功率MOSFET的压降,用户可选择逐个脉冲式限流,或打呃式过流保护。

TPS43000可以在低功耗模式下工作,有欠压锁定,软起动等功能,最高工作频率达2MHz。

IC的内部等效电路如图1所示。

其16PIN功能描述如下:1 PIN SYNC/SC此功能端用于外同步及关断控制,要求外脉冲从0V~2V,占空比不限,但脉宽必须大于100ns。

保持此端高于2V,或保持此电压达35μS,IC 即关断。

2 PIN CCS限流端子,可逐个脉冲电流限制及打呃式限制,将此端接于VIN,为逐个脉冲限流,接此端到GND,进入打呃式过流保护。

3 PIN RT外接电阻到GND设置工作频率。

4 PIN CCM无论输入端检测有没有信号,I ZERO比较器都允许断续型工作,将此端电平拉高,可忽视I ZERO比较器的输出,强制连续导通模式工作,将其接地,即使能I ZERO,允许断续导通模式工作。

式中: KIND 是一个系数, 代表了电感纹波电流相对最大输出电流,推荐值为 0.2~0.3。 (4) 钳位二极管 D1 该款 TPS5430 在 PH 和 GND 之间接外部钳位二极管。选定的二极管必须满足 大于该系统的绝对最大额定值:反向电压必须比最高 PH 电压还高,这是 VINMAX + 0.5, 峰值电流必须大于 IOUTMAX 再加上峰峰值电感电流一半。 重要的是要注意 该二极管传导时间通常长于高侧 FET,因此重视对二极管参数配置可以使整体效率 显着提高。对于这个二极管,反向电压 40V,正向电流 3 A,正向压降为 0.5V。

②升压电容器 在 PH 引脚与 BOOT 引脚之间接一个 0.01μF 的低 ESR 陶瓷电容。 这电容器提 供了高边 MOSFET 栅极驱动电压。 ③输出反馈(VSENSE)和内部补偿 该稳压器输出电压是由反馈到 VSENSE 管脚由外部电阻分压器设定的。在稳态 运行时,VSENSE 管脚电压应等于参考电压 1.221V。该款 TPS5430 实现内部补偿, 以简化稳压管的设计。由于该款 TPS5430 采用电压模式控制,为了提供高交叉频率 和高稳定性的相位裕度,芯片设计采用Ⅲ型补偿网络[8]。 ④电压前馈 尽管输入电压有变化,内部电压前馈提供恒定直流功率级增益。这大大简化了 稳定性分析,提高了瞬态响应。前馈电压随输入电压的峰值斜坡电压成反比,使调 制器和功率级增益是在反馈增益不变的情况下,TPS5430 典型的前馈增益为 25。 ⑤脉宽调制(PWM)控制 该稳压器采用固定频率脉宽调制( PWM)控制方法。首先,利用高增益误差 放大器和补偿网络将反馈电压(VSENSE 管脚电压)与参考恒压相比较的,产生误 差电压。然后,由 PWM 比较器将误差电压与斜坡电压进行比较。这样,误差电压 幅度转换为脉冲宽度即占空比。最后,PWM 的输出反馈到栅极驱动电路来控制上 高边 MOSFET 的开通时间和频率。 ⑥过流保护 过电流保护是通过检测高侧 MOSFET 的漏源电压来动作。然后将漏源电压与 代表过流阈值的临界电压值相比较。如果漏源电压超过过流阈值临界值,过电流标 志位设置为真。该系统将在每个周期的开始时忽略前沿消隐时间的过流指示,以避 免任何噪声故障。 一旦过流标志设置为真,过流保护被触发。高侧 MOSFET 在一定的延迟后将 关闭,为下个周期作准备。过电流保护是所谓的循环周期电流限制。如果检测电流 在逐周期电流限制期内继续增加,将触发过电流保护的“间歇”模式替代逐周期限流 模式。在“间歇”模式过流保护,参考电压接地且高侧 MOSFET 为关闭,下次“间歇” 作准备。一旦“间歇”持续时间完成,调节器在慢启动电路控制下重启。

TPS54331中文资料

TPS54331中文资料

TPS54331【用途】电源管理/DC-DC转换电路【性能参数】采用双列贴片8引脚封装。

用于以3.5V 至28V 的输入电压提供3A 的输出电流低至0.8V 的可调输出电压。

开关频率被内部设置为570kHz(hertz)赫兹的额定频率。

提供可调节慢启动和欠电压锁定输入。

TPS54331EVM-232 输入电压的最大绝对值是30V。

是一款采用Natural Interleaving技术的双相位功率因子校正(PFC)控制器以及最新SWIFT的DC/DC电源管理转换器。

技术特征:◆Eco-mode:轻载情况下自动进入跳周期模式,可以提高轻载条件下的系统效率。

跳周期模式并不是在TPS54331中首次应用,也不是TI首次应用,它是一种被广泛应用的成熟技术,不过TI为其借用了一个好听的名字,Eco-mode意为经济模式或者节能模式,在显示器、电视机、UPS、投影机等用电设备的说明书中,这个名词也常见,TI则将这个名词用于器件而不是整机或者单元电路中,并为之注册了商标:◆SWIFT:TI专门为其DC-DC电源管理器件开发的软件设计工具,借用SWIFT名称并申请了商标;有两种含义,一种是指SocietyWorldwideInterbankFinanciaLTElecommunation(环球同业银行金融电讯协会)的缩写,该协会的成员银行都有自己特定的SWIFT代码,即SWIFTCODE (代码),它相当于各个银行的身份证号,在该协会内是唯一的,其作用是减少各银行间业务错误的发生几率,各国知名银行,也包括国内的几家银行都是该协会的成员;作为单独一个词,SWIFT含义是迅速的。

◆待机模式的电流消耗约lμA;◆570kHz固定开关频率:◆逐周期限流保护,过热关断,输出级晶体管过压保护,可编程的输入欠压锁定,软启动时间可设定及至关断,折频保护。

折频保护的原理是在电路启动期间和电流过载时降低开关频率以降低电感中的冲击电流,这种保护机理有“釜底抽薪”之妙,已经被广泛应用,常见的中文译名是“频率折叠”或者“频率折返”(从易于理解的角度来说,这些译名值得商榷)。

德州仪器高性能单片机和模拟器件在高校中的应用手册-电源

德州仪器高性能单片机和模拟器件在高校中的应用和选型指南-电源部分黄争编著德州仪器半导体技术(上海)有限公司大学计划部2010 年6月前言作为世界领先的半导体产品供应商,TI 不仅在DSP的市场份额上有超过65%占有率的绝对优势;在模拟产品领域,TI 也一直占据出货量世界第一的位置。

而本手册是针对中国大学中创新和科研应用的简化选型指南,帮助老师和同学们快速了解TI的模拟产品。

需要提醒大家的是,这本手册仅仅涵盖了TI模拟产品的一小部分,如果您需要更为全面细致的选型帮助和技术文档,请访问/analog以获取运算放大器,数据转换器,电源管理,时钟,接口逻辑和RF等产品信息,访问 /mcu 以获得更多MSP430,M3和C2000的产品信息。

本手册将分为以下几部分介绍TI的产品和在大学生电子设计竞赛中的一些解决方案:第一章: 介绍TI概况第二章:介绍TI精密信号链产品;包括精密运算放大器,SAR和Delta-Sigma ADC及工业现场中的信号调理、采集和传输;第三章:介绍精密信号链中的噪声问题和应对方案;第四章:介绍TI高速信号链产品;包括高速运放、流水线型ADC及通信系统中的信号调理、采集和传输;第五章:介绍高速运放和ADC中的PCB设计;第六章:介绍TI的电源产品;包括一次电源,低功耗系统供电和中小功率供电方案;第七章:介绍如何有效地对开关电源进行布局和PCB设计;第八章:介绍TI单片机家族和最新的M3开发板简介和开发流程;第九章:介绍TI在设计和仿真阶段提供的一系列免费设计工具和技术文档索引。

第十章:介绍TI大学计划对中国大学的特殊支持:如何有效申请TI免费样片;特价小批量销售的相关细节;以及本手册中所介绍的芯片汇总。

本手册主要着眼于选型,因此一些涉及深入的技术细节的章节在本手册中略去,大家可以参考我们的培训PPT。

本手册所附的光盘里含有这些培训资料、本手册中芯片的数据手册和评估板资料、模拟和单片机的应用笔记、各系列单片机的设计文档、Protel格式的原理图和PCB图以及各种源代码、历年TI杯优秀论文选、设计软件等等,共计2.2GB。

The EVM is designed to operate properly with certain components above 60°C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User’s Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.Mailing Address:Texas InstrumentsPost Office Box 655303Dallas, Texas 75265Copyright 2002, Texas Instruments IncorporatedV O (AC)50 mV/divV I = 5 V 40 µs/divV O (AC)50 mV/divV I = 5 V 20 µs/divV I = 5 VI O = 3 A400 ns/divV O (AC)10 mV/divV I = 5 VI O = 3 A400 ns/divV I (AC)50 mV/divV I (2 V/div)V O (2 V/div)V (5 V/div)13。
