Description: Dual Step-Down Converter

Features

* High Efficiency: Up to 95%
* Output Current: see Table 1
* Input Voltage Range: 2.7V to 5.5V
* Output Voltage Range: 1.2V to 3.6V (available in 100mV steps)
* Constant Frequency Operation: 2.0MHz
* 180º Out of Phase Operation
* Low Battery Detection
* Low Dropout Op

Applications

* In shutdown mode the typical supply current decreases to ≤1μA. The highly efficient duty cycle (100%) provides low dropout operation, prolonging battery life in portable systems. An internal synchronous switching scheme increases efficiency and eliminates the need for an external Schottky diode. Th
