LT1301IS8#PBF
Boost (Step Up) Switching Regulator, Fixed, 1.8V-10V In, 12V Out, SOIC-8
제품 개요
The LT1301IS8#PBF is a micropower step-up DC/DC Converter utilizes Burst Mode™ operation. The device can deliver 5 or 12V from a two-cell battery input. It features programmable 5 or 12V 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 for soft start or to program peak switch current with a single resistor allowing the use of even smaller inductors in lighter load applications.
