Semtech Corp. has received MIL-PRF-19500/406 qualification from Defense Supply Center Columbus, (DSCC) of its brand new 1.5W Zener diode voltage regulator platform. Semtech Corp. has received ...

There are many small applications where it would be preferable to power a device directly from an RS232 (V.24) interface, avoiding a mains power supply. Most ICs require 5 V, and the interface can ...

Figure 2 Bootstrapping the IC switch voltage to the input in the circuit of Figure 1 improves efficiency by about 3%. Of course, the FET actively turns on when the source goes low. But simply using ...
