Overview
LT1300 Micropower High Efficiency 3.
3/5V Step-Up DC/DC Converter FEATURES s s s s s s s s s s s DESCRIPTION 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-fold reduction over prior designs.
A 155kHz internal oscillator allows the use of extremely small surface mount inductors and capacitors.
Operation is guaranteed at 1.
8V input.
