L6920 Datasheet (STMicroelectronics) - 1V HIGH EFFICIENCY SYNCRONOUS STEP UP CONVERTER

L6920, 1V HIGH EFFICIENCY SYNCRONOUS STEP UP CONVERTER

The L6920 is a high efficiency step-up controller requiring only three external components to realize the conversion from the battery voltage to the selected output voltage.

The start up is guaranteed at 1V and the device is operating down to 0.6V.

Internal synchronous rectifier is implemented with
