MICROPOWER VFM STEP-UP DC/DC CONVERTER
The APE2902 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
APE2902 accept a positive input voltage from start-up
voltage to VOUT and convert it to a higher output voltage in
the 2.5 to 5V range.
The APE2902 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 APE2902 is suitable to be used in battery powered
equipment where low noise, low ripple and ultra low supply
current are required. Operating shutdown function is outside
controlling. If EN connects to GND, the IC was been shut
down and then the supply current is lower to 1uA.The
APE2902 is available in very small package: SOT-23-5L.
Typical applications are pagers, cameras & video
camera, cellular telephones, wireless telephones, palmtop
computer, battery backup supplies, battery powered
equipment.
