AX5503 MICROPOWER VFM STEP-UP DC/DC Converter
性能描述:
The AX5503 is a high efficiency VFM Step-up DC/DC converter for *all,low input voltage or battery powered systems with ultra low quiescent supply current.The AX5503 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 AX5503 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 *all,low cost inductors.Only three external components are needed an inductor a diode and an output capacitor.
The AX5503 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 than the supply current
is lower to 1uA.The AX5503 is available in very *all package: SOT-23-5L.
T*ical applications are pagers,cameras and video camera, cellular ephones,wireless ephones, palm* computer,battery backup supplies, battery poweredequipment.
特点:
• Very Low Supply Current is 22uA (t*.)
• Maximum shutdown current <1uA
• Output voltage is available form 2.2V to 5.0V by 0.1V steps
• Output Voltage Accuracy &plu*n;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-23-5L Pb-Free
