The LT1619ES8#TRPBF is a low voltage current mode PWM controller designed by Linear Technology for implementing current mode DC/DC converters with minimal external components. It operates across a wide input voltage range of 1.9V to 18V, making it suitable for various battery-powered and distributed power supply applications.
This controller features a fixed operating frequency of 300kHz, which can be synchronized externally up to 500kHz. It includes a 1A rail-to-rail N-channel MOSFET driver and a low 53mV current limit threshold voltage to improve efficiency. The LT1619 supports topologies such as boost, SEPIC, and flyback converters requiring low-side power transistors.
Efficiency is further enhanced at light loads through Burst Mode operation. The device has a no-load quiescent current of 140mA and a shutdown current of 15mA. It is available in an 8-lead MSOP or SO package, suitable for surface mount applications.
Key electrical characteristics include a wide VIN range, fixed frequency current mode control, and an internal current sense amplifier with leading edge blanking. The LT1619 is well-suited for 3.3V to 5V DC/DC converters, distributed power supplies, and isolated power supplies.
