Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

BCM：电感电流连续工作模式（周期结束时电感电流刚好降为0） 看电感电流是否连续可以从每个周期的电感电流是否从0开始来判断。 这两种电路本质解释就是电压发生变化的电路。但是官方名称又叫单管不隔离直流变化。 单管：续流二极管。作用：续流。

The MAX5073 is a dual-output DC-DC converter with integrated high-side n-channel power MOSFETs. Each output can be configured either as a buck converter or a boost converter. The device is capable of ...

Texas Instruments' TPS63000 helps extend battery life in smart phones, digital still cameras and other single-cell, Li-ion-powered devices by providing high-efficiency buck-boost power conversion.

Linear Tech has brought out a synchronous current mode monolithic buck-boost converter that delivers up to 5A of continuous output current in buck mode from a wide variety of input sources, including ...

Designing a circuit is a lot easier on paper, where components have well-defined values, or lacking that, at least well-defined tolerances. Unfortunately, even keeping percentage tolerances in mind ...

The synchronous buck converter is a widely used topology in low-voltage, high-current applications. One common application is a point-of-load (POL) converter that transforms a system bus voltage of 48 ...

Generally when you crack open a cheap car-to-USB charger unit that came with some widget, you do not expect to find anything amazing inside. That’s why it was such a surprise to [Big Clive] when said ...
