LT1618 Constant-Current/ Constant-Voltage 1.4MHz Step-Up DC/DC Converter FEATURES s s s s s s s DESCRIPTIO Accurate Input/Output Current Control: ±5% Over Temperature Accurate Output Voltage Control: ±1% Wide VIN Range: 1.6V to 18V 1.4MHz Switching Frequency High Output Voltage: Up to 35V Low VCESAT Switch: 200mV at 1A Tiny 10-Pin MSOP Package U APPLICATIO S s s s s The LT®1618 step-up DC/DC converter combines a traditional voltage feedback loop and a unique current feedback loop to operate as a constant-current, constant-voltage source. This fixed frequency, current mode switcher operates from a wide input voltage range of 1.6V to 18V, and the high switching frequency of 1.4MHz permits the use of tiny, low profile inductors and capacitors.
