Analog Devices, Inc. Ultralow Noise 2A Switching Regulator LT1534IS#PBF

Description
Product Details The LT1534/LT1534-1 are 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. The LT1534/LT1534-1 can reduce high frequency harmonic power by as much as 40dB with only minor losses in efficiency. The LT1534/LT1534-1 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. Low minimum supply voltage and low supply current during shutdown make the LT1534/LT1534-1 well suited for portable applications. The LT1534/LT1534-1 are available in the 16-pin narrow SO package.
