Product Overview

The LT1300CS8#PBF is a micropower step-up DC/DC Converter that utilizes Burst Mode™ operation. The device can deliver 5V or 3.3 from a two-cell battery input. It features programmable 5 or 3.3V output via a logic-controlled input, no-load 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. This allows more energy to be extracted from the battery increasing operating life. The ILIM pin can be used to program peak switch current with a single resistor allowing the use of less expensive and smaller inductors and capacitors in lighter load applications.
  • Up to 88% efficiency
  • Shutdown to 10µA
  • ILIM Pin programs peak switch current
  • Uses inexpensive surface mount inductors
  • 10µH Small inductor
  • 120µA Quiescent current
