(ST5R00 Series) MICROPOWER VFM STEP-UP DC/DC CONVERTER

® ST5R00 SERIES MICROPOWER VFM STEP-UP DC/DC CONVERTER s s s s s s s s s s VERY LOW SUPPLY CURRENT REGULATED OUTPUT VOLTAGE WIDE RANGE OF OUTPUT VOLTAGE AVAILABLE (2.5V, 2.8V, 3.0V, 3.3V, 5.0V) 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 VERY SMALL PACKAGE: SOT23-5L, SOT-89 SOT23-5L SOT-89 DESCRIPTION The ST5R00 is an high efficiency VFM Step-up DC/DC converter for small, low input voltage or battery powered systems with ultra low quiescent supply current. The ST5Rxx 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 ST5R00 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 nedeed: an inductor a diode and an output capacitor. The ST5R00 is suitable to be used in a battery powered equipment where low noise, low ripple and ultra low supply current are required. The ST5R00 is available in very small packages: SOT23-5L, SOT-89. Typical applications are pagers, cameras & video camera, cellular telephones, wireless telephones, palmtop computer, battery backup supplies, battery powered equipment.
