电源技术 DN457宽输入电压范围同步降压稳压器
 
The LTC®3610 is a high power monolithic synchronousstep-down DC/DC regulator that can deliver up to 12Aof continuous output current from a 4V to 24V (28Vmaximum) input supply. It is a member of a high currentmonolithic regulator family (see Table 1) that featuresintegrated low RDS(ON) ...
电源技术 自举偏置高输入电压降压型控制器
 
High voltage buck DC/DC controllers such as the LTC3890(dual output) and LTC3891 (single output) are popular inautomotive applications due to their extremely wide 4V to60V input voltage range, eliminating the need for a snubberand voltage suppression circuitry. These controllersare also w ...
电源技术 陶瓷输入电容可导致过压瞬变
 
A recent trend in the design of portable devices has beento use ceramic capacitors to filter DC/DC converter inputs.Ceramic capacitors are often chosen because of theirsmall size, low equivalent series resistance (ESR) and highRMS current capability. Also, recently, designers havebeen loo ...
电源技术 LT1300和LT1301在功率DCDC转换器中的应用
 
The design of battery-powered equipment can often bequite challenging. Since few ICs can operate directly fromthe end-of-life voltage from a 2-cell battery (about 1.8V),most systems require a DC/DCconverter. The systemdesigner often has a limited area in which to place the DC/DC converter ...
单片机编程 SCY99090应用指南
本文着重介绍高效低纹波DC-DC降压稳压器SCY99090的特性、典型应用电路、电路中元器件的选型以及PCB的布局。
单片机编程 XL6003 300KHz 36V Boost 3W LED
The XL6003 regulator is fixed frequency PWM Boost (step-up) DC/DC converter, capable ofdriving 1050mA load current with excellent line and load regulation. The regulator is simple to use because it includes internal frequency compensation and a fixed-frequency oscillator so that it requires a minimu ...
