Constant-Current/Constant-Voltage 1.4MHz Step-Up DC/DC Converter

Description

The LT1618 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. The current sense voltage is set at 50mV and can be adjusted using the IADJpin.Available in the 10-Pin (3mm x 3mm) Exposed Pad DFN and 10-pin MSOP packages, the LT1618 provides a complete solution for constant-current applications.ApplicationsLED Backlight DriversUSB Powered Boost/SEPIC ConvertersInput Current Limited Boost/SEPIC ConvertersBattery Chargers
