LT1619 - Low Voltage Current Mode PWM Controller
LT1619 - Low Voltage Current Mode PWM Controller - Linear Technology（凌力尔特）
The LT1619 is a fixed frequency PWM controller for implementing current mode DC/DC converters with minimum external parts. The LT1619 operates with input voltages ranging from 1.9V 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 nonbootstrapped mode or from the output in bootstrapped operation. The driver is designed to drive a low side power transistor inboost, SEPIC, flyback and other topologies.
Converter efficiency is improved at heavy loads with a53mV current sense voltage and at light load with Burst Mode operation. The operating frequency is internally setat 300kHz. The oscillator can also be synchronized externally up to 500kHz. No load quiescent current is 140μA and shutdown current is 15μA.
The LT1619 is available in 8-lead MSOP and SO packages.
