瑞萨移动手持设备移动电话解决方案
方案描述:
Renesas Electronics supplies a broad lineup of products for cellular phone applications. Chief among them are the application processors in the EMMA Mobile and SH-Mobile series, devices that support full HD video processing, and the solutions in the Medity and SH-Mobile G series, chips that combine a baseband processor and an SH-Mobile processor in a single package. Our High-Power Amplifier (HPA) modules support the wireless communication standards used worldwide, and we also offer RFICs. Additionally, Renesas Electronics also produces sub-MCU products that support pedometer, touch-key, and other cellular phone functions. New models of cellular phones are expected to provide ever more sophisticated functionality as communication speeds increase, camera pixel counts rise,LCDdisplays increase in size and resolution. There is a growing demand for features such as the ability to receive and record 1seg TV broadcasts and to handle electronic distribution of video and audio content. Consequently, low power consumption is critical in order to maintain adequate operating time when the user is communicating or the phone is in standby mode. Also, the control functions must be compact so handsets can be thinner and weigh less.

【基础】开关电源中的阻尼振荡图(1)是一个典型的Buck-Boost电路
通常,对类似图(1)的开关电源电路分析时,总假定元件是理想的。
即:忽略磁材料的非线性,忽略电感的电阻和电容的等效电阻,忽略晶体管和二极管的管
设计完板子不知道背景求教最近在写写一篇论文设计了一个电路buck型DC-DC 的开关电源24v直流转化成5V 1A直流的实际背景有哪些?希望大神们求教什么意思呢?就是说我这个电路在哪可以应用上我把24v转成5v
