FEATURES
Low IQ High Light Load Efficiency Synchronous Boost Converter●
DESCRIPTION
● Deliver 3.3V at 60mA from a Single Alkaline/Ni-MH or 3.3V at 120mA from Two Cells● Up to 94% Efficiency
● Low Shutdown Current: < 1μA
● Low Quiescent Current: 12μA.
● Low No-load Input Current (see Typical Perfor- mance Characteristics for detail)
● Output Disconnect by Shutdown Function
● Small SOT23-6 Package
●
APPLICATIONS
● Wireless Mice● Medical Instruments
● Smart Phones
● Bluetooth Devices That is base on constant Off Time/PSM controller topology. It stays in operation with supply voltages down to 0.7V. The implemented boost converter is based on a constant Off Time/PSM controller topology using an internal synchronous rectifier to obtain maximum efficiency. A low-EMI mode is implemented to reduce ringing and in effect lower radiated electromagnetic energy when the converter enters the discontinuous conduction mode.
