LT3800 Overview
LT3800 High-Voltage Synchronous Current Mode Step-Down Controller DESCRIPTIO The LT®3800 is a 200kHz fixed frequency high voltage synchronous current mode step-down switching regulator controller. The IC drives standard gate N-channel power MOSFETs and can operate with input voltages from 4V to 60V. An onboard regulator provides IC power directly from VIN and provides for output-derived power to minimize VIN...
