Product Summary
The LT1618EMS is a constant-current/voltage 1.4MHz step-up DC/DC converter. The LT1618EMS 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 of the LT1618EMS is set at 50mV and can be adjusted using the IADJ pin.
