■ DESCRIPTIO The LT®3439 is a push-pull DC/DC transformer driver that
reduces conducted and radiated electromagnetic interference (EMI). Ultralow noise and EMI are achieved by
controlling the output switch voltage and current slew
rates. Slew rates are user adjustable to optimize output
noise versus efficiency. The LT3439 can reduce high
frequency harmonic content by as much as 40dB with only
a minor decrease in efficiency. Reduced Conducted and Radiated EMI
