The LT1619ES8#TRPBF is a fixed frequency PWM controller designed for implementing current mode DC/DC converters with minimal external components. It operates with a wide input voltage range of 1.9V to 18V, making it suitable for various battery-powered and distributed DC/DC converter applications.
This controller features a 1A rail-to-rail N-channel MOSFET driver and a low 53mV current sense voltage for improved efficiency. It supports multiple topologies including Boost, SEPIC, and Flyback converters requiring low-side power transistors. The internal current sense amplifier includes leading edge blanking. Converter efficiency is further enhanced at light loads with Burst Mode operation.
The LT1619ES8#TRPBF operates at an internally set frequency of 300kHz, which can be synchronized externally up to 500kHz. It has a no-load quiescent current of 140mA and a shutdown current of 15mA. The device is available in an 8-lead SOIC package and is suitable for surface mount applications.
Typical applications include 3.3V to 5V DC/DC converters, distributed power supplies, and isolated power supplies. The controller's features make it a versatile choice for power management designs requiring efficient and stable voltage conversion.
