"电源管理指南"
本指南详细阐述了电源管理的各种技术和解决方案,适用于不同的应用场景。电源管理在现代电子设备中扮演着至关重要的角色,它不仅关乎设备的能效,还直接影响到系统的可靠性和电池寿命。
一、便携式与线性电源解决方案
这部分涵盖了针对便携式设备(如手机、笔记本电脑)以及线性电源的解决方案。便携式电源方案关注的是高效能源转换和低功耗,以延长设备的运行时间。线性电源则侧重于稳定电压输出和低噪声,适合对电源质量要求较高的应用。
二、AC/DC与隔离型DC/DC电源供应
AC/DC转换是将交流电转换为直流电的过程,通常需要功率因数校正(PFC)来提高输入电流的谐波质量。隔离型DC/DC转换器则用于在两个电气隔离的电源之间传输能量,以确保安全并防止相互干扰。
三、功率因素校正(PFC)
PFC技术旨在改善电源的输入电流波形,使其接近正弦波,从而提高系统效率并减少电网污染。常见的PFC方法有连续导通模式(CCM)和非连续导通模式(DCM)。
四、PWM与谐振控制器
脉宽调制(PWM)控制器用于控制开关电源的开关频率和占空比,以调节输出电压。谐振控制器则利用谐振电路实现零电压或零电流切换,以提高效率和降低电磁干扰。
五、门驱动器
门驱动器是控制功率半导体开关(如MOSFET或IGBT)的关键组件,它们提供必要的驱动信号,确保开关器件的快速、可靠工作。
六、非隔离型电源模块
包括降压(Buck)、升压(Boost)和负输出模块,这些模块提供了集成化的电源转换解决方案,简化了设计过程,提高了系统的可靠性。
七、DC/DC开关稳压器
包括降压、升压/反激、SEPIC(单端初级电感转换器)和反相转换器等多种类型,满足各种电压转换需求。对于便携式和线性电源应用,这些转换器是核心组件。
八、线性稳压器
单端和双端线性稳压器(LDO)提供稳定的电压输出,具有低噪声和高精度特性,适合对电源纹波要求严格的场合。
九、电池管理系统产品
包括电池充电器解决方案、电池保护、电池电量计和电池及周边设备认证。电池充电器保护功能确保安全充电,而电池燃料表则能够准确估计电池剩余容量。
十、射频电源解决方案
涵盖射频DC/DC转换器和射频功率探测器,用于无线通信和射频信号处理设备,确保射频信号的稳定和高效。
十一、NexFET™功率MOSFET
NexFET功率MOSFET是一种高性能的半导体开关元件,适用于高效率、高密度的电源设计。
十二、电池管理
包括锂离子电池保护解决方案,防止过充、过放和短路等潜在危险,以及电池和周边设备的认证机制,确保系统安全。
十三、无线电源
无线电力传输技术允许设备无接触地接收电力,TI提供的解决方案可能涉及Qi等无线充电标准,方便用户使用。
总体来说,德州仪器(TI)提供的电源管理解决方案覆盖了从电源输入到输出的整个链路,包括转换、控制、保护和优化等方面,为各类电子设备提供高效、可靠的电源支持。

Nano Modules
The new SIMPLE SWITCHER nano modules combine
ease of use and high performance in a tiny solution size.
The nano modules boast the smallest 1-A package in
the market today. It’s the first integrated inductor solu-
tion with the IC mounted on the inductor to reduce
board space requirements and improve performance,
making them superior for space-constrained, point-of-
load applications.
Easy-to-Use Package
The new nano module packaging size of
2.5 x 3 x 1.2 mm, makes it the tiniest 1-A
DC/DC solution in the market. By mount-
ing the IC on a shielded inductor, the
nano modules provide a complete solu-
tion that requires only an input capacitor,
an output capacitor, a V
CON
capacitor,
and feedback resistors in 35 mm
2
of
board space.

Non-Isolated Plug-In Power Modules (POLA™ and Others) Family of Products
The PTH08T220W is a high-performance, 16-A-rated, T2 point-of-load (POL) power
module. Operating from an input voltage range of 4.5 V to 14 V, the PTH08T220W
requires a single resistor to set the output voltage to any value over the range of 0.7 V
to 5.5 V. The PTH08T220W incorporates TurboTrans technology, SmartSync and
Auto-Track™ sequencing.
