如图１、２所示，ＭＡＸ１６５２－ＭＡＸ１６５５是高效率的ＰＷＭ降压控制器，这些器件具有很高的工作占空比（９９％）以适应更低的压差，可低至１Ｖ的输出电压和更低的静态工作电流特性。在ＰＤＡ和笔记本电脑等手持应用中，可保证更长的待机时间。ＭＡＸ１６５２／ＭＡＸ
As shown in Figure 1 and Figure 2, the MAX1652-MAX1655 are high efficiency PWM step-down controllers that feature a high duty cycle (99%) to accommodate lower voltage drops and output voltages as low as 1V And lower static operating current characteristics. In handheld applications such as PDAs and laptops, longer standby times are guaranteed. MAX1652 / MAX
