LT1618
Constant-Current/
Constant-Voltage 1.4MHz
Step-Up DC/DC Converter U FEATURES DESCRIPTIO ■ 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. The current
sense voltage is set at 50mV and can be adjusted using the
IADJ pin. ■
