这本书展示了最常见的硬开关电源拓扑和移相全桥软开关的波形和方程。所有的方程都是理想的，唯一的例外是考虑了整流二极管和续流二极管的正向电压。所有这些方程也可以在德州仪器的Power Stage Designer工具中使用。

The PW5300 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2Ω powerMOSFET make this regulator highly power efficient. The internal compensation network alsominimizes as much as 6 external component counts. The non-inverting input of error amplifierconnects to a 0.6V precision reference voltage and internal soft-start function can reduce the inrushcurrent. The PW5300 is available in the SOT23-6L package and provides space-saving PCB for theapplication fields

The PW5200A/ PW5200C is high efficiency synchronous, PWM step-up DC/DC converters optimizedto provide a high efficient solution to medium power systems. The devices work with a 1.4MHz fixedfrequency switching. These features minimize overall solution footprint by allowing the use of tiny,low profile inductors and ceramic capacitors. Automatic PWM/PFM mode switching at light loadsaves power and improves efficiency
