1 / 7 page  Advanced Power Electronics Corp. FEATURES DESCRIPTION Very Low Supply Current Regulated Output Voltage Wide Range of Output Voltage is Available from 2.2V 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 Low Profile: SOT-23, SOT-89 & SOT-23-5L Pb-Free Data and specifications subject to change without notice 201208301 APE2903 TYPICAL APPLICATION ORDERING INFORMATION 1 MICROPOWER VFM STEP-UP DC/DC CONVERTER 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 2.2V 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. 47uH D1 B140 C3 47uF VIN APE2903 SW GND NC NC Vout 100uF C1 OUT L1 0.1uF C2 0.1uF C4 Package Type Y5 : SOT-23-5L APE2903X - XX 25 : 2.5V 50 : 5.0V VOUT 26 : 2.6V 27 : 2.7V : N : SOT-23 G : SOT-89 22 : 2.2V |
