APE1910
STEP-UP PFM DC/DC CONVERTER
DESCRIPTION
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 package size and fewer tiny external
components are required in the application to save space
and lower cost. APE1910 is available in SOT-23-5L
