General Description
The AT1301 is a high efficiency step-up DC/DC
converter for applications using 1 to 4 cells battery.
Only three external components are required to
deliver a fixed output voltage of 3.3V, 5V. This
device employ VFM for minimum supply current
at low loads.
The VFM control circuit operating in 100kHz
(typ.) switching rate results in smaller passive
components. The small SOT-89 packages make the
AT1301 an ideal choice of DC/DC Converter for
space conscious applications.
