SKIP CYCLE
CURRENT LIMIT
We recommend a pin 1 operation between 400 mV and
1.3 V that will fix the skip peak current level between
120 mV/Rsense and 390 mV/Rsense.
NonLatching Shutdown
In some cases, it might be desirable to shut off the part
temporarily and authorize its restart once the default has
disappeared. This option can easily be accomplished
through a single NPN bipolar transistor wired between FB
and ground. By pulling FB below the Adj pin 1 level, the
output pulses are disabled as long as FB is pulled below
pin 1. As soon as FB is relaxed, the IC resumes its operation.
Figure 19
depicts the application example.
