TPS62410: MODE/DATA 引脚说明

PIN MODE/DATA 两个功能：2. EasyScale，这个功能怎么进入？进入后会怎么样？

Johnsin Tao：

HI

     Datasheet中pin脚定义说明得很清楚： （或者你看一下datasheet中得功能介绍，page10页7.33，  14/15页7.5.15）

    This Pin has 2 functions:

      1. Operation mode selection: With low level, power-save mode is enabled where the device operates in PFM mode at light loads and enters automatically PWM mode at heavy loads. Pulling this PIN to High forces the device to operate in PWM mode over the whole load range. 

      2.  EasyScale interface function: One wire serial interface to change the output voltage of both converters. The pin has an open-drain output to provide an acknowledge condition if requested. The current into the open-drain output stage may not exceed 500 μA. The interface is active if either EN1 or EN2 is High.
