LTC3805IDD Integrated Circuit Chip Adjustable Frequency Current Mode Flyback DC/DC Controller
Product Description Of LTC3805IDD
LTC3805IDD is a current mode controller for flyback DC/DC converters designed to drive an N-channel MOSFET in high input and output voltage converter applications. Operating frequency and slope compensation can be programmed by external resistors. Programmable overcurrent sensing protects the converter from short-circuits. Soft-start can be programmed using an external capacitor and the soft-start capacitor also programs an automatic restart feature.
