LT1300CS8#PBF

LT1300 is a micropower step-up DC/DC converter that utilizes Burst Mode™ operation. It features programmable 5V or 3.3V output via a logic-controlled input, onload 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. 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. It is used in application such as palmtop computers, portable instruments, bar-code scanners, DC/DC converter module replacements, battery backup supplies, personal digital assistants, PCMCIA cards etc.
