V that will fix the skip peak current level between 120 mV
/ RSENSE and 390 mV / RSENSE.

We recommend a pin 1 operation between 400 mV and 1.3
In some cases, it might be desirable to shut off the part

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.
