Diode Selection
The current in the external diode (D1 in Figure 1)
changes abruptly from zero to its peak value each time
the LX switch turns off. To avoid excessive losses, the
diode must have a fast turn-on time and a low forward
voltage.
Make sure that the diode ’ s peak current rating exceeds
the peak current limit set by the current limit, and that
its breakdown voltage exceeds V IN . Use Schottky
diodes when possible.
MAX1776 Stability
Instability is frequently caused by excessive noise on
OUT, FB, or GND due to poor layout or improper com-
ponent selection. Instability typically manifests itself as
“ motorboating, ” which is characterized by grouped
switching pulses with large gaps and excessive low-
frequency output ripple during no-load or light-load
conditions.
PC Board Layout and Grounding
High switching frequencies and large peak currents
make PC board layout an important part of the design.
Poor layout introduces switching noise into the feed-
back path, resulting in jitter, instability, or degraded
performance. High-power traces, highlighted in the
