LT1534CS#PBF

LT1534 is a new class of switching regulator designed to reduce conducted and radiated electromagnetic interference (EMI). Ultralow noise and EMI are achieved by providing user control of the output switch slew rates. Voltage and current slew rates can be independently programmed to optimize switcher harmonic content versus efficiency. It can reduce high frequency harmonic power by as much as 40dB with only minor losses in efficiency. It utilize a current mode architecture optimized for low noise boost topologies. The ICs include a 2A power switch along with all necessary oscillator, control and protection circuitry. Unique error amp circuitry can regulate both positive and negative voltages. It is used in application such as precision instrumentation systems, isolated supplies for industrial automation, medical instruments, wireless communications, single board data acquisition systems etc.
