电源技术 LTP5901 and LTP5902 Hardware Integration Guide
The LTP5901 and LTP5902 require little external circuitry, as the devices references,decoupling and power supply filtering are integrated. The LTP5901 and LTP5902 will bemodularly certified for operation in the United States (FCC), Canada (IC) and theEuropean Union (CE).
电源技术 LED的电源管理
A light-emitting diode (LED) is a semiconductor device that emits narrow-spectrum incoherent light when forward-biased.The color of the emitted light depends on the chemical composition of the semiconductor material used, and can benear-ultraviolet, visible or infrared. LEDs are more prevalent tod ...
电源技术 电能计量和安全性的智能电网
Abstract: It may sound trite, but it is definitely true: the smart grid has the potential to completely transform the energyindustry. However, smart meters and grid management alone will not ensure the success of the smart grid. Unliketraditional IT networks, smart grids require consideration of e ...
电源技术 电平转换控制功率MOSFET
Abstract: Some power architectures require the power supply sequencer (or system manager) to controldownstream power MOSFETs to allow power to flow into branch circuits. This application note explains howsystem power sequencing and level shifting can be accomplished using a low-voltage system mana ...
电源技术 如何保护集成FET的电源开关
Abstract: Some types of loads require more current during startup than when running. Other loads can be limited to a lower-powercurrent during startup but require a higher operating current. This article describes an application circuit that automatically adjusts apower circuit’s overcurrent ...
电源技术 简单、高效USB电源管理IC解决方案
 
Linear Technology offers a variety of devices that simplifyconverting power from a USB cable, but the LTC®3455represents the highest level of functional integration yet. The LTC3455 seamlessly manages power flowbetween an AC adapter, USB cable and Li-ion battery,while complying with U ...
电源技术 低电压FPGA的高性能开关电源解决方案
 
The core voltages for FPGAs are moving lower as a resultof advances in the fabrication process. The newest FPGAfamily from Altera, the Stratix® II, now requires a corevoltage of 1.2V and the Stratix, Stratix GX, HardCopy®Stratix and CycloneTM families require a core voltage of1.5V ...
电源技术 单片同步稳压器驱动外部元件负载
 
The LTC®3414 offers a compact and efficient voltage regulatorsolution for point of load conversion in electronicsystems that require low output voltages (down to 0.8V)from a 2.5V to 5V power bus. Internal power MOSFETswitches, with only 67mW on-resistance, allow theLTC3414 to deliver ...
电源技术 DN383 高电压电流模式降压转换器
 
Low power standby requirements are typically associatedwith battery-powered systems. Automotive systems,for example, commonly require power supplies tomaintain output voltage regulation even under no-loadconditions—while drawing minimal quiescent current topreserve battery life. Ris ...
电源技术 DN384 精确的电源排序,防止系统损坏
 
Many complex systems—such as telecom equipment,memory modules, optical systems, networking equipment,servers and base stations—use FPGAs and otherdigital ICs that require multiple voltage rails that muststart up and shut down in a specific order, otherwise theICs can be damage ...
