LT3439l low noise switching architecture


Posted on Aug 30, 2012

Figure 1 shows the LT®3439, one of several low noise switchers available from Linear Technology. Ultralow noise and low EMI are achieved by controlling both the output switch voltage and current slew rates. This switching architecture is particularly well suited to noise-sensitive systems such as industrial sensing and control, data conversion and wideband communications.



DC/DC push-pull topologies like the one shown in Figure ½¡1 are commonly used in low noise systems because they offer relatively low input ripple current to the power supply circuit. Nevertheless, DC/DC switcher topologies generate high frequency ha
