FEATURES
s DESCRIPTIO s s s s s Low Quiescent Current: 20µA in Active Mode <1µA in Shutdown Mode Operates with VIN as Low as 1V Low VCESAT Switch: 250mV at 300mA Uses Small Surface Mount Components High Output Voltage: Up to – 34V Tiny 5-Lead SOT-23 Package U APPLICATIO S s s s s LCD Bias Handheld Computers Battery Backup Digital Cameras The LT®1617/LT1617-1 are micropower inverting DC/DC converters in a 5-lead SOT-23 package. The LT1617 is designed for higher power systems with a 350mA current limit and an input voltage range of 1.2V to 15V, whereas the LT1617-1 is intended for lower power and single-cell applications with a 100mA current limit and an extended input voltage range of 1V to 15V. Otherwise, the two devices are functionally equivalent. Both devices feature a quiescent current of only 20µA at no load, which further reduces to 0.5µA in shutdown. A current limited, fixed offtime control scheme conserves operating current, resulting in high efficiency over a broad range of load current.
