Buck DC-DC Converter IC
The TCV7101F is a single-chip buck DC-DC converter IC.
The TCV7101F contains high-speed and low-on-resistance power
MOSFETs to achieve synchronous rectification using an external
low-side MOSFET, or rectification using an external diode,
allowing for high efficiency.
Features
Enables up to 3.8 A of load current (I
OUT
) with a minimum of
external components.
High efficiency:

Incorporates an N-channel MOSFET driver for synchronous rectification
Uses internal phase compensation to achieve high efficiency with a minimum of external components.
Allows the use of a small surface-mount ceramic capacitor as an output filter capacitor.
Housed in a small surface-mount package (SOP Advance) with a low thermal resistance.
Soft-start time adjustable by an external capacitor

This product has a MOS structure and is sensitive to electrostatic discharge. Handle with care.
The product(s) in this document (“Product”) contain functions intended to protect the Product from temporary
small overloads such as minor short-term overcurrent, or overheating. The protective functions do not necessarily
protect Product under all circumstances. When incorporating Product into your system, please design the system (1)
to avoid such overloads upon the Product, and (2) to shut down or otherwise relieve the Product of such overload
conditions immediately upon occurrence. For details, please refer to the notes appearing below in this document and

Five outstanding advantages of TD-SCDMA
当然世界上没有完美的技术,都在不断演进替代之中。TD的主要问题是对同频干扰敏感(上下行同频,不同的基站和手机,上下行之间都相互干扰),网络和终端之间的同步要求高,基站覆盖范围有限,而且对手机移动速度有限;技术优势也不代表市场优势,还要看能否尽快成熟稳定商用,这才是目前最困难的。据说目前TD刚刚完成LCR 语音和64kbps数据测试,384kbps数据还在测试中,2Mbps还没有影子,HSDPA只是...
