The APE1913 is a current mode step up
converter intended for small, low power
applications. The converter input voltage ranging
from 2.6V to 5.5V. The Output voltage can be set
up to 27V. The frequency is 1.2MHz allows the use
of small external inductors and capacitors and
provides fast transient response. Internal soft start
results in small inrush current and extends battery
life. Internal power MOSFET with very low RDS
(ON) provides high efficiency. The APE1913
automatically transits from PWM to PFM during
light load condition further increasing efficiency.
The converter also provides protection functions
such as under-voltage lockout, current limit and
thermal shutdown. The APE1913 is available in
TSOT-23-5L package.
