Product Overview

The LT1534CS#PBF is a 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. The LT1534 can reduce high frequency harmonic power by as much as 40dB with only minor losses in efficiency. The LT1534 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. The internal oscillator may be synchronized to an external clock for more accurate placement of switching harmonics. Protection features include cycle-by-cycle current limit protection, undervoltage lockout and thermal shutdown.
  • Greatly reduced conducted and radiated EMI
  • Low switching harmonic content
  • Independent control of switch voltage and current slew rates
  • Regulates positive and negative voltages
  • Easily synchronized to external clock
  • Easier layout than with conventional switchers
  • 12µA Typical low shutdown current
