The LTC3783EFE#PBF is a versatile current mode LED driver and boost, flyback, and SEPIC controller manufactured by Analog Devices. It is designed to drive both an N-channel power MOSFET and an N-channel load PWM switch, enabling true PWM load switching with minimal transient issues.
Key features include a wide operating frequency range from 20kHz to 1MHz, which can be set with an external resistor. It supports both analog and PWM dimming, achieving high dimming ratios. The controller includes a 1.23V internal voltage reference with 1% accuracy and a 7V low dropout internal regulator. It also offers a low shutdown current of 20µA.
This controller is suitable for applications requiring constant current or constant voltage regulation. It can be used in a No RSENSE mode for improved efficiency in certain applications. The device is available in a 16-lead TSSOP package with an exposed pad, designed for surface mounting.
Applications include high voltage LED arrays, telecom power supplies, and 42V automotive systems.
