APE1910

STEP-UP PFM DC/DC CONVERTER

1

The APE1910 is a Pulse Frequency Modulation (PFM)

DC/DC converter. It is Low quiescent current 30uA and

shutdown current less 1uA. The APE1910 feature a wide

input voltage. The operating voltage is ranged from 1.2V to

12V. It also feature low quiescent current, switching current

limiting, low temperature coefficient.

Smaller

size

and

fewer

tiny external

components are required in the application to save space

and lower cost. APE1910 is available in SOT-23-5L
