Tame Switching Supply Noise While Maintaining Efficiency

by Samuel Kerem , Electronic Design, Dec 11 2008

Focus:
A low-noise switching regulator such as the LT1533 in combination with an electronically adjustable resistor forms the basis for a switched-mode power supply with very low noise and EMI as well as high efficiency.

What you’ll learn:

• How to build a low-noise, low-EMI dc-dc converter
• How to reduce a switcher's EMI and noise by controlling the slew rate of the output switch
