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 隔离电源设计手册
Abstract: This document details the Oceanside (MAXREFDES9#) subsystem reference design, a 3.3V to 15V input,±15V (±12V) output, isolated power supply. The Oceanside design includes a high-efficiency step-up controller, a36V H-bridge transformer driver for isolated supplies, a wide in ...
电源技术 如何设计一个高效率的DC-DC转换器
Abstract: The DS1875 features a pulse-width modulation (PWM) controller that can be used to control aDC-DC converter. The DC-DC converter can then be used to generate the high bias voltages necessaryfor avalanche photodiodes (APDs). This application note describes the operation of a boost converte ...
电源技术 DN1011 简单高效率隔离型反激式电源
 
While simplicity and high effi ciency (for cool running) areno longer optional features in isolated power supplies, itis traditionally diffi cult to achieve both. Achieving higheffi ciency often requires the use of advanced topologiesand home-brewed secondary synchronous rectifi cationsch ...
电源技术 超低功率转换器的控制方案消除开关噪声
 
An essential component of a noise-free audio device isa clean power supply, but few switching regulators canoperate at high efficiency while keeping the switchingfrequency out of the audio band. The LTC®3620 fills thisvoid. It is a high efficiency 15mA buck regulator with aprogrammabl ...
电源技术 具有100uV输出噪声的单片开关稳压器
 
Size, output flexibility and efficiency advantages havemade switching regulators common in electronic apparatus.The continued emphasis on these attributes hasresulted in circuitry with 95% efficiency that requiresminimal board area. Although these advantages are welcome,they necessitate c ...
