APE2903
MICROPOWER VFM STEP-UP DC/DC CONVERTER
DESCRIPTION
The APE2903 is a high efficiency VFM Step-up DC/DC
converter for small, low input voltage or battery powered
systems with ultra low quiescent supply current. The
APE2903 accept a positive input voltage from start-up
voltage to VOUT and convert it to a higher output voltage in
the 2.2 to 5V range.
The APE2903 combine ultra low quiescent supply
current and high efficiency to give maximum battery life. The
high switching frequency and the internally limited peak
inductor current permits the use of small, low cost inductors.
Only three external components are needed an inductor a
diode and an output capacitor.
The APE2903 is suitable to be used in battery powered
equipment where low noise, low ripple and ultra low supply
current are required. The APE2903 is available in very small
package: SOT-23, SOT-89 & SOT-23-5L.
Typical applications are pagers, cameras & video
camera, cellular telephones, wireless telephones, palmtop
computer, battery backup supplies, battery powered
equipment.
