The LT3800IFE#PBF is a high-voltage synchronous current mode step-down switching regulator controller manufactured by Analog Devices. This IC is designed to drive standard gate N-channel power MOSFETs and supports input voltages ranging from 4V to 60V. It operates at a fixed frequency of 200kHz.
Key features include an onboard regulator for IC power, dynamic bootstrap for MOSFET drivers, and Burst Mode operation that reduces no-load quiescent current to under 100μA. It also incorporates a reverse inductor current inhibit for improved light-load efficiency and a programmable soft-start feature to control output voltage slew rate, reducing startup surge currents and overshoot errors.
The LT3800IFE#PBF is suitable for applications such as 12V and 42V automotive power supplies, 48V telecom power supplies, avionics, industrial control systems, and distributed power converters. It offers 1% regulation accuracy and reverse overcurrent protection.
This component is available in a 16-lead thermally enhanced TSSOP package with an exposed pad, designed for surface mounting.
