Product Overview

The LT1619ES8#PBF is a low voltage current mode PWM Controller for implementing current mode DC/DC converters with minimum external parts. The LT1619 operates with input voltages ranging from 1.9 to 18V and is suitable for a variety of battery-powered and distributed DC/DC converters. The internal rail-to-rail N-channel MOSFET driver operates either from the input in the non-bootstrapped mode or from the output in bootstrapped operation. The driver is designed to drive a low side power transistor in boost, SEPIC, flyback and other topologies. Converter efficiency is improved at heavy loads with a 53mV current sense voltage and at light load with Burst Mode®® operation. The operating frequency is internally set at 300kHz. The oscillator can also be synchronized externally up to 500kHz. No load quiescent current is 140µA and shutdown current is 15µA.
