The LT3845EFE#PBF from Analog Devices is a high voltage, synchronous, current mode controller designed for medium to high power, high efficiency supplies. It offers a wide input voltage range from 4V to 60V, with a minimum start-up voltage of 7.5V. An onboard regulator simplifies biasing requirements by providing IC power directly from VIN.
This controller supports Burst Mode operation, maintaining high efficiency at light loads by reducing quiescent current to 120μA. It also features a reverse inductor current inhibit function for improved light load efficiency. Additional capabilities include adjustable fixed operating frequency from 100kHz to 500kHz, which can be synchronized to an external clock for noise-sensitive applications. The device includes gate drivers capable of driving large N-channel MOSFETs, a precision undervoltage lockout, 10μA shutdown current, short-circuit protection, and a programmable soft-start.
The LT3845EFE#PBF is available in a 16-lead thermally enhanced TSSOP package with an exposed pad. Its applications include 12V and 42V automotive and heavy equipment, 48V telecom power supplies, avionics, industrial control systems, and distributed power converters.
