1-A SIMPLE STEP-DOWN SWITCHING VOLTAGE REGULATORS
SLVS638B – MAY 2006 – REVISED JANUARY 2007
APPLICATION INFORMATION (continued)
The power and ground connections of the TL2575 and TL2575HV must be low impedance to help maintain
output stability. For the 5-pin packages, both pin 3 and tab are ground, and either connection can be used as
they are both part of the same lead frame. With the 16-pin package, all the ground pins (including signal and
power grounds) should be soldered directly to wide PCB copper traces to ensure low-inductance connections
and good thermal dissipation.
With any switching regulator, circuit layout plays an important role in circuit performance. Wiring and parasitic
inductances, as well as stray capacitances, are subjected to rapidly switching currents, which can result in
unwanted voltage transients. To minimize inductance and ground loops, the length of the leads indicated by
heavy lines should be minimized. Optimal results can be achieved by single-point grounding (see Figure 2) or by
ground-plane construction. For the same reasons, the two programming resistors used in the adjustable version
should be located as close as possible to the regulator to keep the sensitive feedback wiring short.
