如图所示的ＭＡＸ１６８７／ＭＡＸ１６８８升压型ＤＣ—ＤＣ转换器采用一种独特的控制方式，它是专为“猝发负载”系统如ＧＳＭ手机而优化设计的。这种方式通过限制电池峰值电流，精确控制ＰＡ（功放）储备电容的充电速率，从而避免了这类应用中采用传统的升压转换器时浪涌１
The MAX1687 / MAX1688 step-up DC-DC converters shown in the figure have a unique control scheme that is optimized for “burst-load” systems such as GSM handsets. This approach accurately controls the charging rate of the PA (power amplifier) reserve capacitor by limiting the peak battery current, thereby avoiding surges when using conventional boost converters in such applications
