引言CoolSET ICE2B265是内带CoolMOS的集成脉宽调制器。它含有控制器和CoolMOS功率开关，价格便宜。设计者可以用它来实现当前各种新型开关电源，例如要求待机功耗低、外部元件少，电路板面积最小等等。如图1所示，CoolSET的控制部分采用了一些特别的增强方法来实现低待机功耗 Introduction The CoolSET ICE2B265 is an integrated pulse width modulator with CoolMOS. It contains the controller and CoolMOS power switch, the price is cheap. Designers can use it to achieve the current variety of new switching power supply, for example, requires low standby power consumption, fewer external components, the smallest circuit board area and so on. As shown in Figure 1, the control section of CoolSET uses some special enhancements to achieve low standby power
