1 / 8 page  Advanced Power Electronics Corp. FEATURES DESCRIPTION Very Low Supply Current is 22uA (typ.) Maximum Shutdown Current <1uA Output Voltage is Available form 2.5V to 5.0V by 0.1V Steps Output Voltage Accuracy ±5% Output Current up to 100mA Low Ripple and Low Noise Very Low Start-up Voltage High Efficiency (Vout = 5V TYP. 87%) Few External Components Internal Soft-Start Low Profile: SOT-23-5L Pb-Free Identification Code see page8. Data and specifications subject to change without notice 200907313 APE2902 TYPICAL APPLICATION ORDER/MARKING INFORMATION 1 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.
