PCMCIA Cards Burst Mode is a trademark of Linear Technology Corporation. U ■ The LT1300 is a micropower step-up DC/DC converter that
utilizes Burst Mode™ operation. The device can deliver 5V
or 3.3V from a two-cell battery input. It features programmable 5V or 3.3V output via a logic-controlled input, noload quiescent current of 120µA and a shutdown pin which
reduces supply current to 10µA. The on-chip power switch
has a low 170mV saturation voltage at a switch current of
1A, a four-f...
