單開關(guān)(或稱單晶體管)正激轉(zhuǎn)換器是一種最基本類型的基于變壓器的隔離降壓轉(zhuǎn)換器，廣泛用于需要大降壓比的應(yīng)用。這種轉(zhuǎn)換器的優(yōu)點包括只需單顆接地參考晶體管，及非脈沖輸出電流減小輸出電容的均方根紋波電流含量等。但這種轉(zhuǎn)換器的功率能力小于半橋或全橋拓?fù)浣Y(jié)構(gòu)，且變壓器需要磁芯復(fù)位，使這種轉(zhuǎn)換器的最大占空比限制在約50%。此外，金屬氧化物半導(dǎo)體場效應(yīng)管(MOSfet)開關(guān)的漏電壓變化達(dá)輸入電壓的兩倍或更多，使這種拓?fù)浣Y(jié)構(gòu)較難于用在較高輸入電壓的應(yīng)用。

高的工作電壓高達(dá)100V N雙N溝道MOSfet同步驅(qū)動 The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifi er provides very fast line and load transient response. Large 1Ω gate drivers allow the D810DCDC to drive multiple MOSfets for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. Integrated bias control generates gate drive power from the input supply during start-up and when an output shortcircuit occurs, with the addition of a small external SOT23 MOSfet. When in regulation, power is derived from the output for higher effi ciency.

DC/DC 升壓IC：The FP6291 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.25 Ω power MOSfet make this regulator highly power efficient. The internal compensation network also minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects to a 0.6V precision reference voltage and internal soft-start function can reduce the inrush current. The FP6291 is available in the SOT23-6L package and provides space-saving PCB for the application fields.

Traditionally, an Electronic Circuit Breaker (ECB) comprisesa MOSfet, a MOSfet controller and a current senseresistor. The LTC®4213 does away with the sense resistorby using the RDS(ON) of the external MOSfet. The resultis a simple, small solution that offers a signifi cant lowinsertion loss advantage at low operating load voltage.The LTC4213 features two circuit breaking responses tovarying overload conditions with three selectable tripthresholds and a high side drive for an external N-channelMOSfet switch.

The LTC3546 is a dual output current mode buck regulatorwith fl exible output current partitioning. Beyondthe advantages normally associated with dual outputregulators (reduced size, cost, EMI and part count, withimproved effi ciency), the LTC3546’s outputs can bepartitioned for either 3A and 1A outputs, or two 2A outputs.This increases its application range and simplifi esmultiple supply rail designs. A confi gurable Burst Mode®clamp for each output sets the current transition levelbetween Burst Mode operation and forced continuousconduction mode to optimize effi ciency over the entireoutput range. An adjustable switching frequency up to4MHz and internal power MOSfet switches allow forsmall and compact footprints.
