Features

* 4.5 V to 40 V wide input voltage range
* 600 mA continuous output current
* 60 µA standby, 0.3 µA shutdown current
* 1% output voltage accuracy
* 1.05 MHz and 2.1 MHz fixed switching frequency
* Pulse Frequency Modulation (PFM) option for light load

Applications

* in industrial and automotive environments. 0.3 µA ultralow shutdown supply current allows use in batterypowered applications. High power conversion efficiency across a wide load range is achieved by folding down the switching frequency at light load condition reducing the switching losses. Frequency
